I usually support cop suggestions, but I have many doubts regarding yours:
1. A tazer's range should be a shouting range... Cuz many of us have high ping issues so it makes the message "OUT OF RANGE" to appear. (remember it they have a poor skill too so they can't move fast)
I think the current range is good enough; increasing the range would make it too easy.
It could be considered a good idea to take the cop's ping into account and increasing the range based on it, but since it's easy to fake a high ping (using the ping amplifier), it would be easily abused.
2. We can taze a yellow or 1-star suspect as everyone knows that we will call our personal vehicle and run away from that cop. (it's so annoying to cops as they can't do anything. If did anything like taking him out from the vehicle... a new topic will start by the suspect if he does /report)
I agree with tazing yellows and even innocents, but ONLY if they are posing a threat or potential threat. I don't agree in tazing them to avoid them running.
However, I do agree that the tazer should work on everyone except cops.
3. If we hit a suspect (that's in a vehicle) he will fall from that bike or if he is in a car he can't control his player (movement buttons) for 5 seconds.
Only on a bike (or quad). Also 5 seconds is way too much.
4. Ability to turning off the engine by firing on a vehicle for 7 seconds (1 hit) and if the suspect is in a chopper then 3 shots if he's in a plane then 5/6 shots to turning their engine off for 7 seconds.
I don't agree. It makes no sense.
5. also a little one, increase the storage of tazer's ammo as many peeps miss their shot (me) and start shooting unarmed.
Yes.
