My dad used to be a cop, but we asked him to do an early retirement... Cops are being generalized nowadays because majority of them are abusive. :(
Not all cops are bad, there are just some who abuses their power...
And as for the post, I chose B... I didn't see the whole thing, so I can't do any assumptions. ;)
The power they wield is bad in and of itself.
That could be true... They're there to serve and protect, not the other way around. :)
Who do they serve? The government. Who do they protect? One another from liability.
Ideally, they have to protect and serve the people, but realistically... it's as you have mentioned above. :(
