Xfinity security sounds like a joke

Read the fine print. $29.95 first 12 months then 39.95 for 36 months. The small print says it will only cost me
A total of $1,318.20 for home security. Great deal huh? Seems Comcast is trying to corner another market. But call me crazy but if I was a thief I would simply cut the cable wire going to the house then I would simply disable the persons xfinity cable,phone,Internet and now the home security.
