YMCAs begin to screen for sex offenders

This is an issue that came up in the beginning of January I wanted to comment on.
Here's the article:  YMCAs begin to screen for sex offenders
I am not a YMCA member, but this banning business is frustrating and crazy, in my opinion.

So the YMCA implemented this policy after a girls basketball coach, who was not a convicted sex offender when he was hired or when coaching, plead guilty to various sex offenses with young girls. I suppose the Y feels they have to do something showing they are "protecting" members, especially since it's less of a traditional gym and more of a mixed adult/kids place, but chalk this up as another reactive policy to sex offenders.

The Y is instituting a policy that doesn't directly address how they could have let a coach with a clean record come in and coach young girls he ended up offending against.  If the Y needs to find sex offenders among their members and staff, the only way to be sure is to have staff (this offender could be considered staff) and members undergo a thorough evaluation including personality testing, penile plethysmography, the female equivalent to a penile plethysmograph, and attentional evaluation to deviant stimuli.  Just ranting but what the hell...
