The question of the police in a free society is a complex and potentially polarizing one. Being a policeman or policewoman is a nasty, demanding job. It is very dangerous and police officers regularly do heroic things. Because of the stress and the job demands, they have poor marital records and many broken families.
Unfortunately, it leads to some bad fallout. They come in contact day after day with the very worst elements of society. It tends to make them cynical about people. It also tends to make them band together with a “brothers in blue” mentality that makes them loath to report officers who may be in trouble and should not be on the streets with a badge and a gun.
Also, they are human. We, as a society, want to hold them to a higher standard just as we do our political leaders. Because of the police culture, which is changing, but slowly, they haven’t gotten ongoing training and on-the-job support to keep cops from taking corruption, to weed out cops with streaks of violence or on power trips, to educate about racial sensitivity. We need to do more for them.
At the same time, the police as a group (which of course they are not) are viewed by the black community completely justifiably as racist. There is a not a black man in America in any walk of life who has not been stopped for no reason and to some extent, at least verbally, harassed by the police. Our justice system as a whole (not holding the police solely responsible for this) is definitely racist. That is clear from conviction rates and the sentences and even the executions for the same types of crimes.
Is it any wonder that a militant part of the black community is stirred up by any situation that can be inflamed into a racial altercation?
I do not believe that the whole black community in Twinsburg believes the type of rhetoric that was on the site you linked to, which was a very militant one.
What we have to do is 1) Work hard to eliminate racial profiling and the injustices with regard to race in our justice system as a whole. 2) Meet as communities to work through racial divides. 3) Then try to view each incident as an individual one and not throw it into the stew of racial polarization.
