Read Radley Balko's "Rise of the Warrior Cop." It goes into great detail as to the reasons and history as to why we are where we are at this time and it also offers some solutions. You could also read Jill Lavoy's "Ghettoside" if you want to read about cops who do their jobs well and by the book. Both books give the reader some insight as to the problems police face and some solutions.
Stop militarizing the police. This has lead to an 'us vs them' mentality. The polices job is to 'Protect and serve' not search and destroy. Very few PDs need armored vehicles and associated weaponary.
Community based policing. Have cops actually walking a beat and getting to know the people they are paid to protect and serve. Some cities have begun to incoporate this idea, notably San Diego, with positive results.
Increased training for officers. Particularly in the area of how to de-escalate a volital situation.
Cross the 'Thin Blue Line.' Police officers are reluctant to call out each other. The good cops need to start throwing the bad cops under the bus. The officer in Minn. kneeled on that guys neck for almost 8 minutes chocking him to death. None of the other cops there stepped in. 2 were rookies. This cop had numerous complaints against him but the FOP and his fellow officers saw to it he would face no consequences.
End no knock search warrants. Literally thousands of innocent peaole have been killed and maimed by theses since Regan pushed this garbage through in his zeal to fight the war on drugs. It was a bad idea then and still is. ALSO search warrants need to face more vetting. All too many times a judge grants a search warrant based upon flimsey evidence or claims by 'paid informants.' Look at the case of the EMT lady who was shot 8 times in a no knock raid based upon some extremely dubious statements made to obtain said warrant.
Require body cams and require said cam to be operative ANY time a LEO interacts with the public. No exceptions.
