OPINION OF THE COURT
Aaron Oliver appeals from a judgment of conviction, after a jury trial, on a charge of possession of a firearm by a convicted felon. 18 U.S.C. App. I § 1202(a)(1). Oliver was sentenced as a dangerous special offender (DSO) under 18 U.S.C. § 3575. Although 18 U.S.C. App. I § 1202(a)(1) carries a maximum sentence оf two years, Oliver was sentenced (as a DSO) to 12 years’ imprisonment.
Oliver raises two issues on appeal. First, he contends that he was denied due process of law and was the victim of prosecutorial vindictiveness when, as the result of his failure to cooperate with state аu *125 thorities, his pending state firearms charge became the subject of a federal indictment. Second, Oliver alleges that the imposition of a 12-year sentence under 18 U.S.C. § 3575, upon his conviction under § 1202(a)(1), was disproportionate to his conviction and excessive. We find both of Olivеr’s arguments to be without merit and affirm the judgment of the district court.
I.
On January 20, 1984, Philadelphia Police Department detectives took Oliver into custody as part of an investigation into the death of Ronald Luckett. When arrested, Oliver, a convicted felon, possessed a loaded .38 caliber revolver. On January 30, 1984, Oliver was charged with firearms violations.
Assistant District Attorney Arnold Gordon informed Oliver’s attorney, Daniel-Paul Alva, that he wanted Oliver to cooperate with the Philadelphia Police in the investigation of the Luckett homicide. Gordon allegedly told Alva that, if Oliver fаiled to cooperate or flunked a lie detector test, Oliver’s state firearms charge would be referred to federal authorities for prosecution. Alva advised his client to cooperate with the Philadelphia Police and expressed his belief that, in return for Olivеr’s cooperation, the state firearms charges would be withdrawn or subjected to an entry of nolle prosequi.
What transpired in state court is not entirely clear. It appears that Oliver cooperated with the state authorities to some degree and that they dropped the statе charges against him, but that they ultimately deemed his cooperation to be insufficient and thus alerted the federal authorities to the fact that Oliver, a convicted felon, possessed a firearm. At all events, on October 19, 1984, the United States Attorney’s Office for the Eastern District of Pеnnsylvania issued a complaint and warrant charging Oliver with a violation of 18 U.S.C. App. I § 1202(a)(1). An indictment soon followed. The government also filed a Notice of Request for Dangerous Special Offender Status pursuant to 18 U.S.C. § 3575.
On January 30, 1985, a jury convicted Oliver of a violation of 18 U.S.C. App. I § 1202(a)(1). The court denied Oliver’s motion to dismiss the government’s request for Dangerous Special Offender Status pursuant to 18 U.S.C. § 3575 and sentenced Oliver on March 13, 1985, as a dangerous special offender, to 12 years in prison and a $10,000 fine.
II.
Oliver alleges that his due process rights, as guaranteed by the Fifth Amendment, were violated because his pending state firearms case was referred to the federal authorities for prosecution as a direct result of his failure to cooperate in the Luckett homicide investigation. This deprivation of due process, he contends, is the result оf prosecutorial vindictiveness as described in
Blackledge v. Perry,
The Supreme Court held in
Black-ledge
that it is a due process violation for a prosecutor to bring a more serious charge against a defendant who exercises his statutory right of appeal or collaterally attacks his conviction on a lesser charge.
Blackledge, supra,
The government argues that since the discussions between Assistant District Attorney Gordon and Oliver’s attorney Alva amountеd to plea bargaining, the proscriptions of
Blackledge
do not apply and Oliver’s due process rights were not violated. In
Bordenkircher v. Hayes,
Since Oliver’s theory of the case is that he was prosecuted by federal authorities solely because he failed to cooperate satisfactorily with the Philadelphia Police in the plea bargaining process, this case is governed by Bordenkircher. 1 It is not disputed that defendant’s attorney, Mr. Alva, discussed with Mr. Oliver the decision that confronted him and explained the ramifications of each of his choices. Oliver made an informed decision not to cooperate fully with the police in the Luckett homicide investigation, though he did succeed in getting his state charges dropped. Thus, under the reasoning of Bordenkircher, there was no prosecutorial vindictiveness, for Oliver was fully informed of the consequences of his choices; he freely decided not to cooperate to a greater extent with the local authorities and, as a result, was later indicted by federal authorities.
We need not, however, rest our decision on this analysis alone. Other circuits that have addressed this issue havе found that separate sovereigns have the right to bring increased charges or simultaneous prosecutions for similar or identical offenses and that there is no prosecutorial vindictiveness where the prosecutor’s decision to prosecute is based upon the usuаl determinative factors.
See United States v. DeMichael,
III.
Oliver argues that his 12-year sentence, which the district court imposed pursuant to 18 U.S.C. § 3575, 2 is an excessive penalty for a violation of 18 U.S.C. App. I § 1202(а)(1), which carries a two-year maximum sentence. Oliver buttresses his argument with the assertion that other defendants charged as DSO’s with violation of 18 U.S.C. App. I § 1202(a)(1) have fared better *127 than he. 3 This court is permitted under 18 U.S.C. § 3576 to conduct broad reviews of dangerous special offender sentences. Title 18 U.S.C. § 3576. 4
Olivеr does not contest the district court’s finding that he is a dangerous special offender under 18 U.S.C. § 3575. He argues that the twelve-year sentence imposed violates that part of 18 U.S.C. § 3575. that provides “the court shall sentence the defendant to imprisonment for an appropriate term not to exceed twenty-five years and
not disproportionate in severity to the maximum term otherwise authorized ' by law for such felony
” (emphasis added). Congress added the proportionality requirement to ensure that the sentence for an offense remained at least partially focused on that offense rather than on prior conduct or other factors.
United States v. Felder,
At the sentencing hearing, the district court considered the seriousness of the firearms offense of which appellant had been convicted. The court detailed the conduct that led to Oliver’s classification as a dangеrous special offender: Oliver has been convicted of three counts of forcible rape, receiving stolen goods, and two additional firearms violations. As the presentence investigation report also reveals, Oliver has been arrested nineteen times sincе 1979 on a variety of charges including possession of firearms, possession and manufacture with intent to deliver a controlled substance, receiving stolen property, filing a false police report, aggravated assault and recklessly endangering another person. Mоst of these arrests did not result in Oliver’s conviction, yet Oliver told the U.S. probation officer that he “was fortunate to get off so many times because he was guilty on a majority of the listed cases.” In connection with one conviction, Oliver *128 jumped out of a car and shot a man on а step blinding him in the eye and continued to shoot after the man fell down a set of steps. He is an admitted cocaine dealer with sales on the average of $2,000 per week. He carries firearms “to protect his drug interest.”
Under all the circumstances, we believe the district сourt’s imposition of this augmented sentence was proper. Nowhere does the caselaw suggest that we should use, as a guide to proportionate sentencing, the sentences which other dangerous special offenders convicted under the same federal stаtute receive. In any event, Oliver’s sentence is not so different from the sentenced imposed in United States v. Adams, supra; United States v. Felder, supra; United States v. Davis, supra; and United States v. Boyd, supra, for the same felony conviction. See n. 3, supra.
The judgment and sentence of the district court will be affirmed.

(2) the defendant committed such felony as part of a pattern of conduct which was criminal under applicable laws of any jurisdiction which constituted a substantial source of his income, and in which he manifested speсial skill or expertise; or
(3) such felony was, or the defendant committed such felony in furtherance of, a conspiracy with three or more other persons to engage in a pattern of conduct criminal under applicable laws of any jurisdiction, and the defendant did, or agreed that he would, initiate, organize, plan, finance, direct, manage, or supervise all or part of such conspiracy or conduct, or give or receive a bribe or use force as all or part of such conduct.
