Florida deputy Jesse Hernandez screamed “shots fired,” and frantically fired his gun after an acorn fell onto the roof of his squad car, making him jump.
No, we should never hire people to be cops and then train them. We don't do that with any other people who have command over life and death AND operate autonomously that I can think of except maybe some positions in the military. Even EMT certification is basically "you exist because we need way more EMT's than we could possibly hope to have if being an EMT required a four year degree, and you won't be reasonably expected to do anything other than what we train you to do".
We should require cops to be well trained. Make it a four year degree at a minimum, and let the rage hearted idiots be weeded out in college when they fail all the ethical training courses.
Don't think that applies here. If you need training to know that you shouldn't open fire on a handcuffed man in the back of a squad car because you heard a light "thud" sound, police work is definitely not the job for you.
