Seems that you are assuming some of the following:
...All single and married moms have access to a computer
...That dads, brothers, uncles, grandfathers don't count
...Once access to a computer is available, moms know how/where to log on to check their neighborhood for sex offenders
...Once logged on, that moms know the difference between sex offenders and child predators
...Once they are logged on, they know the lingo each state uses to define category and severity of predators
...you forget the plea bargains between prosecuters, defense attorneys, and judges that allow these low-life slugs to serve short sentences
...you forget that the court SEALS juvenile records and this is where it all starts for the sex predator mho
...you forget about the group and individual therapists who claim rehabilitation can take place
...predators are often paroled over and over because they are thought to be rehabilitated - how bout those???
....How about those who fail to register
...And it seems you are not aware of how cunning, manipulative, and adoring these predators are of single moms and how they stalk to have access to their children
And let's not forget that there are plenty of husbands and wives (couples) who have lost their child to the child predators mho
Fine to be angry at mom, aunt, or child caretaker, but please put , at least, some of the blame where it counts the most - our legal system All the above is mho
