I say not really. Here's why. Cops have fully automatic machine guns, explosives. They kill without being prosecuted. Bottom line, they are entrusted to "serve and protect." Now, do you think there's a snowball's chance in hell a cop could have a felony on his record and be accepted to the force? Why should our standards be any different in the military. We certainly don't want a bunch of recidivistic felons representing our country by murdering or raping civilians across the globe. We should never entrust these ex-cons with such a high and grave job. They have served their time, true, but only their jail time. There is a reason they must disclose their past to employers, gun shop owners, and others. It is because they have acted in such a way as to not deserve our trust. Recidivism is so high among criminals, we are Pollyannaish idiots if we simply turn the other cheek for them to slap it.
If you think we should let felons in the military, then you also must agree we should let felons be cops. The only difference you could claim is that, "Hey they're on the other side of the world. They can't hurt us." Of course that attitude shows a xenophobic disregard for the other citizens of the world.
There is a massive difference. Cops can carry off duty, soldiers cant unless they are in a war zone. Cops take their weapon home, soldiers cannot take their service weapon home. Soldiers cannot just go out and buy a gun if they are a felon. They will be refused just as if they a civilian. A cop's duty weapon is available 24-7, a soldiers is only available on the range (with ammo), in ftx's (with blanks, maybe), or on deployment (with ammo). Of the 1 time every 6 months a soldier is allowed to take his weapon away from the arms room while not deployed and issued ammo, they are not issued ammo until they arrive at the range. They are not allowed to transport their weapons (most have M16's, which are not fully auto) in any method other than by foot or military vehicle. The only time a soldier is unsupervised with his weapon and has ammo is during deployment, and my rounds were counted daily when I was overseas so that is even a stretch. Cops are unsupervised with their weapons 16ish hours a day, seven days a week.
