consequences

There would be a higher percentage of civilian trying police officers because they thought/knew they didn't have a firearm, and others would just plain get shot.

I understand the idea that making cops work through situations without the use of deadly force but you can't send someone into a situation without a firearm.

It works in other countries because their society doesn't have near the amount of gun violence or violence that our country has in general but here, it would be have terrible consequences.
