Do you not think that officers are going to take the easy way out? Let us say, for example, that someone is arrested and charged, and takes exception to that. You said that as soon as the person raises his fist, or does something similar, you could use the weapon to give him a shock. Is that not the easy way out for the officer? Instead of discussing the matter and taking concrete steps to ensure an arrest with no problem, the officer uses the Taser when the suspect does not want to cooperate. He shocks him, he handcuffs him, and Bob's your uncle.
You said that you have to call the ambulance. I was wondering if the municipality pays every time someone is taken to hospital by ambulance. If the Taser was used 215 times between January and July, we can say 500 times. If the municipality has to pay for 500 ambulance trips because of Taser use, it may want to stop paying ancillary costs because they are getting too high.
