A sad, tragic story. A young man is dead. The tazer [[sp?), which is intended to reduce deadly force, is not always safe.....but far more humane and less likely to harm bystanders than a gun.
Investigations will be done, and we can then reach judgments on what went wrong, but two things are evident:
The victim should not have run, or resisted.
The police officers appear to have done nothing against policy.
I support the police, and ask that parents begin teaching their children respect for the police and themselves. When a cop says "stop", you stop!
