Non-Governmental Organizations (NGOs) produce a lot of training materials for law enforcement and other first responders. Contact AAA, the Red Cross, the American Heart Association, and the National Safety Council for some really good stuff about crime prevention, traffic safety, and emergency medicine.
Talk to Your Risk Management and Insurance Companies
Most of our communities either have insurance, or belong to a risk management group, sometimes referred to as a "pool." These organizations tend to focus on two issues: civil liability and employee safety. Since we know that the same things that get you hurt will also get you sued, there is a considerable overlap between these two areas of risk. Approach your insurance company or risk management pool for resources to be used in training officers in the high-risk areas of use of force, motor vehicle operations, and arrest practices.
Some of these groups also provide grants and other funding for equipment purchases. For example, the Michigan Municipal Risk Management Authority provides grants for purchasing TASERs, and for years the Michigan Municipal League would fund part of the cost in purchasing body armor.
These groups and companies also frequently have model policies and other resource documents available. Many also have lending libraries of training materials and videos.
