He doesn’t belong in prison for dong something stupid,
If this happened to an ordinary citizen, he/she would be PROSECUTED, No Questions asked, and considering he shot a POLICE OFFICER, Attempted Murder of a Police Officer charges are in order.
An ordinary citizen would NOT be prosecuted for shooting his/her own finger in a gun shop. It is more likely the employee would be charged for handing the person the loaded gun, but that probably wouldn’t happen either.
Please drop the anti cop bias. He didn’t “attempt” to kill or injure anybody. He acted stupidly and accidentally injured himself.
If the cop or an ordinary citizen had shot one of the customers in the store, charges would be filed.
