I'm troubled by the skepticism regarding the possibility of evil visiting our homes. Yes, TV is an amazing and safe place to live but to leave doors unlocked is an invitation to become a victim. In my previous life I was a drug and alcoholism counselor and believe me, drugs will cause people to take incredible risks and change a docile person into an violent criminal. The local newspaper crime blotter will show you that most of the arrests in the surrounding area revolve around drugs and alcohol. This is true of the entire USA. I'm hardly a fearful person having lived in NYC a good part of my life but I know from experience that vigilence is an important factor is being safe. Sorry about this rant but I was a little disconcerted by the attitude that TV is immune to crime. The people who knock on doors with paper towels sound like grifters who take advantage of the elderly. Pure evil and they travel in packs. My avatar is a picture of my pit bull disguised as a maltese so beware.
