yeah but does a cop have anything powerful enough to tear up a bulldozers tracks?
Probably not. SWAT gets all the nice stuff.
This cements my desire to buy the .50 Beowulf. The gun grabbers might actually have a case to cite for criminal use of a 50.
There is an industry just in repairing bulldozer tracks. They are always coming off the wheels and breaking. Put a rock in there or a piece of metal. It will at least jam the track and maybe knock it off the idler.
