When the stuff hits the fan most people revert back to training & doctrine.
What needs to be brought forward is the training manual and the doctrines.
The Marines storm the objective and overcome. Police departments are not the Marines and I wouldn’t expect them to be.
As I have said and read in other posts along the same lines as this subject, the failure is systemic and it starts with making the target as hard as possible. That is where the failure occurred. The rest is just tragedy because the failure occurred Systemically.
Gibberish. This isn't a systemic problem. It is a failure of one or four trained, paid police officers to do their job. If you include armed security personnel as being part of making the target as hard as possible, then you assume the security personnel will do their job like the DC Capitol police did during the Scalise shooting.
There is no excuse for the four law enforcement officers who were derelict in their duty. Systems don't overcome cowardice.
