Unfortunately this is not really why the Police are here. Their purpose is to:
A: Keep the peace
B: Protect PRIVATE property
C: Act as liaisons between parties that cannot find an agreement
They are most certainly NOT here to protect the public - they are ruled by LAWS, which are fallible by their very own design - and on purpose to keep lawyers employed - remember, laws are made by lawyers.
The police uphold these laws and beyond that are not responsible.
Nowhere does it specify what the police "Serve and protect"
