Assuming I can get a LOUD high frequency horn, and I know where to get a high power amplifier, does anyone know of a particular range of frequencies that I can point toward these criminals that might make them shut the hell up? I'd just push a button after each bark
I don't know about the right frequencies, but if you want to discuss about gauge, I think .22 LR or .38 would be a good start.
