Do you know what the problem with waiting them out is?
$$$$
The vast majority of the departments don’t have the manpower or the money.
It’s that simple.
Is it cheaper than $12 Mil.?
I agree. Waiting out a suspect out costs money.
So then a command decision has to be made. Is the bad guy bad enough to wait him out? If so, wait him out. If not, have your officers continue patrol. Maybe you’ll scoop the bad guy up at a traffic stop, or whatever.
I just don’t think a no-knock raid should be made for financial reasons. It’s too dangerous for everyone involved.
