I sat in court one day when I was 18 -for a drug related offense. Before my case -there were a number of "indecent exposure" cases before me pleading for leniancy. The typical case went like this:
'I was getting ready to take a shower when I remembered that I left my wallet in my car. So I threw on my bathrobe and went out and got it from my car. I guess my neighbor (whom I haven't been getting along with) saw me and called the police. They came to my door and gave me a ticket.'
My point is that these are what people are being arrested for as sex-crimes. If the recidivism rate is low -it's because most people are arrested for trumped up charges.
-If they arrest the right person at all.
