disagree this "scary lawyer letter" scam has nothing to do with the law,
it has to do with a neighbor who is a cry baby who has no case and a lawyer who makes a lot of money off a little old lady who has him on speed dial.
It's a legal lawyer scam. He get's probably $1K for sending a stupid letter, little old lady gets to pay her lawyer to do her bidding instead of walking over and simply saying hey, you tree limb is over my property or whatever.
