Adequately funded police can still take forever to arrive or decide not to come at all. This has absolutely zero to do with defunding police. Which by the way doesn't mean taking -all- of their money away. It means readjusting their budgets and allocating some of that money to other types of responders.

There always has been a market for immediate response private security, if one has the money.

The reality is that police funding has maintained even throughout the "defund movement", so this situation is not caused by police defunding.
