The P.R. problem of Law Enforcement has been created by Law Enforcement institutions, training standards and expectations. Only Law Enforcement can fix the P.R. disaster they have created form themselves.
However it can’t be fixed just with talking points. If you remember Ford and the “Quality is Job One” campaign of the 80’s you will remember that this P.R. campaign was accompanied by a great leap in quality of the Ford products. So sloganeering is not enough. Actions must follow the slogans.
The first step in fixing a problem is realizing there is one, and then wanting to fix it. Not easy to do in this era of political posturing and trying to limit joint and several liability. This applies to The Church, the education system, law enforcement, the Obama administration, the list goes on.
Actually seems to be getting worse.
