In what world does selling a killing machine to a former felon convicted of an aggravated crime make sense? "Well, he paid his debt to society, so he's a de facto free man now and should enjoy all the life, liberty, and happiness pursuits guaranteed by the cons ution." Sex offenders are typically banned from using computers/internet for life, banned for life from being within certain distances of schools, playgrounds, etc. This tramples on the sex offender's freedom of speech and freedom of association rights to a degree, but we all see it as a sensible post-incarceration restriction because sex offenders are recividist threats. Violent felons usually are, too.
