Sounds like an iffy way to solve Problem One while upping the odds greatly on getting involved with Problem Two to me.

It was said earlier, and I concur - anything fired out of a shotgun can be lethal. There was a LEO killed near here a few years back in a training exercise by a blank fired in a shotgun.

Shotguns are lethal force for armed citizens, period. If you are not legally justified in using lethal force, you aren't justified in shooting anything out of a shotgun, no matter what the box the round came in says. Shoot to stop, and use something that has as much of a likelihood of stopping an assault with one shot as you can find. After all, you never know but what one shot is all you might be able to manage.

LEOs who employ less lethal munitions have:

1) training in the use of said munitions, and likely certification in their use as well

2) backup on the scene with lethal weapons at the ready if the less lethal munitions fail to work

3) an official use of force policy that includes the use of less lethal munitions in certain circumstances

4) legal support paid for by the taxpayer

Armed citizens have none of the above... and a different set of legal parameters in the use of force as well. Leave less lethal to the LEOs.
