Beyond fuckhead excuse makers who would probaly just a cop raping someone as long as he heard it was cool from Fox News, Is that Police ARE using these without properly exploring other options. Ever hear of the "Use of Force Continuum"? It's a model police officers are supposed to use to diffuse a situation. Here is a partial model:
Verbal command
Handcuff suspect
Use wrist/arm lock
Use takedown
Block/punch/kick
Strike suspect
Wrestle suspect
Pepper spray
Use baton
Use firearm
Now, As you can see Tasering is left off this list, But it would probably go inbetween Pepper Spray and Use Baton, Possibly even before Pepper Spray (Although I think Mace is a lot safer then passing an Electrical current through someone)
This Issue is, As many an internet video has shown, Is that a lot of police officers are going from Verbal Command to Taser. It's not ok to just go around tasing people who don't sit and beg when a cop snaps their fingers.
