I believe I read on Facebook, my only source since the RG isn't telling us, that the girl was 16 and the guy in his mid 20s. I do not approve of this but it's not the same thing as having sex with children. I don't know how a homeless person with no address can register as a sex offender but maybe there is some way. I presume the point of registration is so the authorities know where the person is. 

The issue here is not whether the guy who got beat up is a good person -- I doubt it -- but whether the police were justified in beating him up. I don't think so. According to what I'm hearing there has been a longstanding police policy of harassing the homeless downtown and this would likely account for the crowd's anger. You cannot solve downtown's problems by harassing people and beating them up. This is pouring gasoline on a fire. People need to start thinking.
