In your opinion, do you feel the Police are losing the publics trust and respect?

In our countries Canada, and the U.S the police have been in the news lately with shootings, and such.
Here in Canada while there has been a few police shootings, one thing just makes me want to barf.
The conductor of that train involved in that disaster in Quebec, was arrested which is fine, but they took him down in his back yard working on his boat in front of his 8 year old kid, with a full blown swat team, like he was some kind of terrorist.
Think that might have been a huge waste of tax dollars ?
Believe me I think the Police have a hard job, and there are a lot of fine officers.
But I feel the police have lost the fact they are there to defend the law,NOT be above it.
