This is a scam, they are not the police calling for donations, if you really want to donate to the local police donate to the PBA of the FOP and they usually do it with mailouts not phone calls
Called and said from some police association. I told him I give to local organizations periodically. He asked when was the last time I gave. I replied I wasn't sure I give periodically throughout the year. He rudely asked again "but when was the last time you gave." So I rudely replied back I wasn't sure. Then he said "fine have a good night."
