I respect laws because they where legislated, debated, and won a majority of votes from a elected body of representatives, that I had the opportunity to participate in selecting. Police are just doing their jobs.
I can understand why you would ask this question if you lived in a miserable dictatorship, where one dictator chose for everyone. But we don't.
We live in a society where you have the right to walk into the parliament and voice you're opinions peacefully. In many countries you would be shot on sight for doing that.
Why do you, not respect the laws?
Not respecting the laws in this country is like not respecting the majority.
You can always voice you're opinion peacefully, or vote with you're feet and move to a dictatorship.
