Some people are just perverted. There are some real freaky men and women out there and mental illness has nothing do with it. Perverts don't need a get out of jail free card. They need solitary confinement. I'm glad they caught him, too often unidentified freaks act really sneaky at these governmental workplaces and Federally-funded programs thinking they can get away with anything. I protect myself by any means necessary.
I never been to Wasilla, rumors suggest its drug-invested because its rural. I recommend obtaining a home security system with actual surveillance and motion detector alarms that will notify emergency services. I also recommend joining or contacting a local neighborhood crime watch for additional resources about personal security devices: panic alarm, door stop, door jammer, mace spray, stun gun, baseball bat, cell phone with SOS, etc...
