I am a backer of the Modesto Police Department. I do not get in trouble. They help when I call about issues at Enslen Park. They are very helpful. With that said, a relative of mine was recently tazered by an MPD officer that brought my relative to his knees. The "residents" at Elk Park (next to Enslen Park) apparently said that it was totally unwarranted and the police overreacted during midday right in front of all onlookers.
There are going to be "loose cannons" in EVERY police department. Not just in Modesto. There are going to be loose cannons in whatever job we work at, whether it is in a police department, fire department, an office, or on an athletic team. Part of my job is managing softball umpires. I have 22 of them to manage. At least 4 of them are "loose cannons" that I have to keep an eye out on and watch their behavior. Your office of 25 employees probably have 3 or 4 "loose cannons." Every work force has good workers, bad workers, nice people, mean people, organized people, scatterbrained people. How is it going to be any different in a police force? No matter what sensitivity training is issued, people are what they are and there is no changing them. They may change for the better temporarily, but ultimately they are going to go back to their old ways.
