radios, no OTHER help, no aircraft to help you spot the guy,and he WILL be shooting at you, quite possibly with a silenced .22 auto rifle. My silencer "how to" books are not the ONLY ones ever sold,andMINE have sold over 150,000 copies. Many of them are read by SEVERAL people, and any one guy can obviously makeandmount SCORES of cans, even without access to electricity. Also, many thousands of can-making "kits" were sold in the early 1980's. Chase a fugitive,(post shtf) u will PROBABLY get shot, simple as that.
