Odds are the real police will never catch the gang in their bogus uniforms.
A team like this will use police radio scanners, lookouts, etc.
At best, they'll find the bogus uniforms in the trunk of somebody's car, and he won't have any idea how they got there, and won't say one more word before lawyering up.
You might think so, but it they're so smart and well organized, why did they hit two dry holes? I doubt they got more than a couple hundred dollars and are now wanted for B&E, impersonating an officer, ADW, kidnapping, armed robbery, and more. They appear to be moronic amateurs to me.
