That lets in "Professional Fund Raisers". The company I did work for obstensively was raising money for a troopers benevolent association. Trouble was it was a handful of troopers who set up their own 501(c), hired this firm, then used around 50K of the money raised/year to send their kids off to camps while the for-profit kept roughly 2 million/year.
IF anybody calls "on behalf" of any cop association, ask them to snail mail you info and a form for sending them money (if you're inclined to help out your "local" police/troopers/fireman's association. Telemarketers are loathe to send you snail mail because they're subject to mail fraud laws - the phone gives them free reign to lie their asses off to you. Apparently, lying is protected speech.
