There are other ways to help police officers feel appreciated and raise morale. America has many empty homes thanks to foreclosures. Give police officers reduced rent or low-cost home loans for their primary residences, and don't have them become neighborhood spies for the privilege, either! It might be especially helpful for crime-ridden communities to refurbish homes to give free housing for police officers and their families in those areas. Give officers and their families free tuition in state colleges.
Abusive police officers make the work environment tougher for everyone. Establish a zero tolerance policy for police brutality, and enforce it. Many more officers would probably report their corrupt partners if they were not afraid of "friendly fire" or being left in a sticky situation without cover one day. Investigate every complaint by the public and all reports law officers make about police misconduct, and do the right thing. Stop all cover-ups today.
Award bonuses periodically to officers who have no complaints in their files. As police brutality and corruption lessen, communities may learn to trust law enforcement and become more cooperative with police investigations. That would improve security for the citizens and engender greater respect for law enforcement from the people who rely on them. It seems that most police officers who do homicides and brutality had numerous misconduct complaints in their files already. The money saved on wrongful death and brutality lawsuits could probably pay for salary increases for all police officers if authorities would stop shielding criminals in uniform.
Pay raises, limits on other employment, opportunities for free or reduced housing and education, plus eliminating abusive cops would raise morale and attract high-quality applicants to police work.
