Police are ineffective at what most people ASSUME is their primary purpose.

If the police where there to protect and serve the common person, than cameras everywhere and a rapid response system to handle any level of hostility would be desirable.

However, police officers are there to protect and serve the govern-cement. They are used as the pointy end of politics. They are mostly used today to collect taxes randomly from mostly innocent people.

It isn't about the drones or not drones, it is about the basis of policing.
The policy.

The whole of the law should be no bigger than the bible.
If you want people to know it and follow it, then that is the largest a normal person could study.
And, study of this book should be a large portion of schooling.

But, the law is specifically obfuscated. It is so large that no one could read it. It is so weasel worded that no one can comprehend it if they did. And any lawyer that told you that they could comprehend it is lying.

Since our police system is based on laws that are only used to intimidate and control the population, than any tool given to the police will be used in that vein. So, police should be given nothing. Every new item should be fought against.
