FTC: Avoid Charity Fraud

Donating to Public Safety Fundraisers

Why do the State Troopers need to solicit donations?
Not 100% positive but, I'd bet the ranch they do draw a salary for their work, and most likely a very handsome benefits package too! Our County Sheriff and Deputies don’t call us begging money. And, they do a hell of a lot more than write tickets on the interstate. They experience way more exposure to violence and injury than the radar runners do.
Not putting them down but, why are they begging when we already pay them?
