Because some people are immune to pepper spray
Immune? How did they know the guy holding the golf club was immune to CS or pepper spray?
Someone can still kill you with a golf club after you pepper spray them.
Woaa....How does that work where there are a dozen fully armed cops standing there? Are you suggesting they would all just stand there and let the homeowner beat one of them to death with his golf club?
It only takes one well placed strike with a club to kill someone. Moreover, the law doesn’t require an officer (or anyone else) to wait to get struck.
