Have to disagree - suspensions are very rare since departments very rarely investigate incidents. During investigations, officers are almost always put on administrative duty and not suspended.
There is probably 3 or 4 threads a day here on FR alone about out of control cops. In the vast majority of the cases no investigation or suspension occurs and the department spokesperson either blames the public for not bowing down or just says that they will look into it.
you said:
Its not cool to rough up old ladies regardless of the situation. However, its also not cool for old ladies to take advantage of their age and expect special treatment.
Special treatment, like not being forced to show your identity papers on your own property? Seems to me that an officious jerk was used to getting away with bullying the public, and found that the public draws the line when you bully little old ladies.
