Standard best-practice protocol states in cases that include weapon involvement, combative victims, overdoses or suicide attempts, police must first secure the scene.That's fine. Safer for everyone, as long as police know where you are. (Don't they have GPS?)
Although the Oakland County sheriff's unit unit was quick to respond to the call, police went the wrong way on the victim's road -- in the opposite direction.Many minutes passed before the medical help - waiting patiently - figured out what happened. The police remained clueless.
Now county officers often cover a huge area. It is impossible for them to know everything. And although everything turned out OK in this incident, it shows up the fact that calling 911 is not a magic solution to all your problems. People make mistakes. Police are minutes away under the best conditions. People get lost, making some minutes many more minutes.
A lot of bad things can happen in that time.
Calling 911 is a fine thing. But it shouldn't be the only thing you do. Learn first aid, CPR, and develop a plan for your personal protection. You need to survive those minutes until help arrives.
