bla bla bla whining because others whine
Ok first of all, the concept of cop work is basically for good-hearted naive people both in real life and in the game. You're not supposed to have it easy just cause you work for the gov., in fact, you're meant to be restricted by regulations, stuck on shitty/average pay despite that you would be earning more as a criminal for similar range of talents (shooting people, in general). In order to have your job easier you get free gear and organized backup. I thought this is kind of obvious. The only wrong matter between criminals and cops is that currently nothing is lost on death (except for some money if you're wanted) which doesn't make much sense.
Second, nobody is whining about taser because it's a new police toy. People are whining because it more or less forces roleplay, which is completely fine when you're running on foot, won't listen to cop orders to give up as you're beating someone up, and so on. However a single hit-kill (it doesn't kill, but getting busted turns out to be worse for those who care about notoriety system - I don't) tool that isn't restricted by scripts has a big potential for abuse, and we already have too many not fully explained, middle-ground, common-sense rules as it is. Again, if carsur shooting is restricted by a script there is simply 0 reasons why taser shouldn't be. How is a newbie for example suppossed to know about the regulation, so he could report it to SAPD authorities if he gets tazed? etc. Keep in mind even the most powerful weapon non-law enforcement gets, the RPG, isn't able to kill someone in one hit (unless someone has low HP.)
I suggest you drop the 'server is cops n robbers' mentality because it's only going in on your head. If not for cops, being a criminal would be pointless. If not for criminals being a cop would be pointless.
