Appellant was convicted of sexual solicitation in violation of D.C.Code § 22-2701 (1984 Supp.). 1 He advances several argu *611 ments on appeal, most of which he did not present to the trial court. We affirm the conviction.
Between 1:00 and 2:00 a.m. on July 7, 1983, appellant approached a woman standing on the corner of 14th and P Streets, N.W. Unknown to appellant, the woman was Officer Gina Giles of the Metropolitan Police, working as an undercover decoy on the prostitution squad. Officer Giles recounted their conversation:
He came to me and said, “Come with me.” And I asked him where. He said that he lived on Rhode Island Avenue. And I asked him, what were we going to go there for? And he told me what he wanted. And I said, well, we had to talk business first and get the money straightened out. He told me he would pay me $10 to screw him.
The officer testified that she understood that “screw” meant a “sexual act” and that, although appellant spoke with an accent, she understood everything he said. 2 As appellant tried to get Officer Giles to walk across the street with him, she made a prearranged signal to her partner, Officer Clinton Williams, who was waiting nearby. Williams came over and identified himself and Giles as police officers. Williams placed appellant under arrest after a brief struggle, despite appellant’s insistence that Giles was his sister. 3
Appellant’s version of the incident was quite different. He said that he merely invited Officer Giles to join him for a drink, even though he thought she was a prostitute. When Officer Williams approached, appellant thought he was Giles’ pimp and was about to “kidnap me and take me away”; that was why he resisted when Williams started to place him under arrest. The trial court credited the testimony of Officer Giles and found appellant guilty as charged. The court specifically found Giles’ testimony that appellant “did ask to screw her for $10 [to be] credible and accurate.” With regard to the possibility of a language barrier, the court found:
I understand that Mr. Eissa is not very fluent or articulate in the English language and has not been in this country for very long. Perhaps he has difficulty understanding what people say to him.
But I find beyond a reasonable doubt that it was Mr. Eissa who did proposition Officer Giles; and despite his limited knowledge of the English language, I think that Mr. Eissa does understand the meaning of the word “screw,” and that it was he, in fact, who did proposition Officer Giles.
At trial appellant’s main contention was that the court should accept his version of the facts as true. The trial court, however, credited Officer Giles’ testimony instead and rejected appellant’s account of what happened. On appeal, therefore, we cannot rely on appellant’s testimony; on the contrary, we must accept the trial court’s findings because they are amply supported by the evidence. D.C.Code § 17-305(a) (1981);
see, e.g., United States v. Lyon,
Appellant makes several challenges to the constitutionality of the sexual solicitation statute. Since none of these arguments were presented to the trial court, we would have to find plain error before we could reverse appellant’s conviction.
See, e.g., United States v. Lewis,
140 U.S.App. D.C. 40, 46,
Even if all of appellant’s claims of error had been properly preserved for appellate review, we would find them merit-less. His vagueness challenge cannot be sustained in light of
Hawkins v. United States,
Appellant also contends (for the first time on appeal) that the statute is unconstitutional as applied. Specifically, he argues that a higher standard of proof must be adopted when the person charged with sexual solicitation is a putative customer of a prostitute rather than the prostitute herself. We cannot accept this argument without overruling
Dinkins v. United States,
Appellant contends that it is a denial of equal protection to require corroboration in cases of homosexual solicitation but not in cases of heterosexual solicitation.
See, e.g., Wajer v. United States,
Finally, appellant argues that the police violated his due process rights by using excessive force to arrest him. Given the facts of the case, we reject this argument.
Washington v. United States,
Affirmed.
Notes
. Section 22-2701 makes it a crime "to invite, entice, persuade, or to address for the purpose of inviting, enticing, or persuading, any person or persons sixteen years of age or over in the District of Columbia, for the purpose of prostitution, or any other immoral or lewd pur-pose_” This portion of the statute was originally enacted in 1935 and has not been changed *611 since then. The next sentence, which was added in 1981, states that inviting, enticing, or persuading "includes, but is not limited to," certain specified types of activity in a public place. D.C.Code § 22-2701.1 (1984 Supp.), which was also enacted in 1981, defines prostitution as "the engaging, agreeing to engage, or offering to engage in sexual acts or contacts with another person in return for a fee.”
. Appellant, a native of Egypt, testified that he had been in the United States for five years.
. Officer Williams corroborated Giles' testimony to some extent. He testified that he saw appellant approach Officer Giles and engage her in conversation, but he was too far away to hear what was said.
. Under M.A.P. v. Ryan, 285 A.2d 310 (D.C. 1971), a decision which is binding precedent, as Dinkins is, can be overruled only by the court en banc, not by a division.
. Appellant bases his argument on our observation in
United States v. Wilson,
