“In making pretrial detention determination, a judicial officer must bear in mind that ‘passage of the pretrial detention provision of the 1984 Act did not…signal a congressional intent to incarcerate wholesale the category of accused persons awaiting trial.” U.S. v. Orta, 760 F.2d 887, 890 (8th Cir. 1985). Rather, Congress was demonstrating its concern about a small but identifiable group of individuals as to whom pretrial release was inappropriate. S. Rep. No. 225 98th Cong. 1st Sess. 6-7, reprinted in 1984 Code Cong. And Ad. News at 3189. U.S. v. Westbrook, 780 F.2d 1185, 1189 (5th Cir. 1986).
