Are we treating our police today like our Vietnam veterans in the 60's & 70's?

With all that's been going on, what are the similarities and/or differences to the way our police are being treated when compared to how our Vietnam vets were treated in the 60's & 70's?

I understand that there are some police officers who abuse their positions of authority, but I suspect that for the most part, police are a reflection of our society and are only trying to do the job they've been told to do - that is namely, enforcing the laws, regardless of how (un)popular they are.

And before anyone goes on saying that all police are evil, let me ask you this: How would you propose that we enforce our laws and apprehend criminals if we don't have police?

Next: If you hate our laws, why do you think the police have any say in enforcing them? Should police simply ignore those laws they don't agree with?

Last: If you don't agree with those laws, when's the last time you wrote or called your local, state, or federal representatives and/or attempted to vote them in/out of office based on the laws they have or say they will make?

See the trend?
