Are you kidding? If they send you a packet, you take it to your local police department and ask to have somebody investigate them. These people are scum and they need to be stopped.
This outfit is a SCAM -- they claim to be calling to collect money for a regional police department, but the Police get pennies on the dollar, if anything. One report indicates that they raised several million dollars in solicitations for one Maryland Sheriffs' Department, but only gave the cops $20K.
