It isn't against the law to be gay. I can't help it, that's the rule. You cannot investigate everyone about whom you have suspicions. And how are you going to explain "sex police" in the House budget?
You are reacting out of emotion (hint, not a good thing) and not with any type of reason.
I don't know if you've been reading the news lately, but if you happen to check the "internets" for information you may find that there was an incident with Congressman Mark Foley sending creepy emails to a 16-year-old former House page.
