Last year in college, a neighbor came to my door freaked out because somebody was peeping on her. Called the local police.
Police officers came to our door told us that peeping toms and flashers had statistical likelihood of escalating their behavior to more and more extreme acts including rape. They already knew the guy based on the neighbor's description. Also said not to fuck around if we saw him again. Any indication of a fixation was a really bad sign.
So should submitter be subject to legal scrutiny, monitoring, and restraint on behavior after that single event? Absolutely. Bad behavior for some, begets worse behavior later. Should submitter be subject to scrutiny, monitoring, and restraint decades after a single offense? Probably not.
We have sexual predator laws for a damn good reason: some people are guaranteed to violently reoffend unless prevented from doing so. Use of those same laws to ensnare teenagers who sext, Romeo & Juliet lovers, and the legitimate one-time offenders, is outside the original law's intent. The issue for the last category of offender is having a legal path to redemption. This piece seems to be missing. Arguable that for a lot of ex-convicts, a path to redemption and unrestrained participation in society is missing.
