I don't think I would feel safe at all. Level 3 sex offenders are very likely to re-offend (and have re-offended before), plus, more often than not, they have predatory tendencies. I'm not sure there are any precautions I could take that would make me feel safe living in that community.
If for some reason I couldn't leave the community and find a safer one, I would make sure my home and my car(s) had active alarm systems. I would also immediately purchase and start carrying some form of self-defense (pepper spray with UV dye, a stun gun) and would consider getting a license for a handgun for protection as well as a license to carry a concealed weapon so I could keep the gun on me at all times.
I don't have children, so I likely wouldn't go out of my way to take precautions, but it would still definitely make me uncomfortable. If nothing else, I like and respect those who live around me, and I would be uncomfortable living that close to someone who in my view is not a great person (sorry). However, I suppose the only real option would be to get used to it.
Lock your doors the same way you always have and go about your business.
I actually had a sex offender living next door for several months. I told my kids (he wasn't a child molester) to stay away from him. He was actually one of my better neighbors.
I wasn't sad to see him move though.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
