There are a few things wrong with the events as it unfolds.
First of all, what are the police doing in this operation when they are dealing with military hardware?
Secondly, the military is not being brought in to diffuse this situation, even though there are hostages involved.
Thirdly, negotiations are underway to understand the gunmen’s demands.
The police are not equipped to deal with the ISIS military. Military gear is required, as well as military tactics. There WILL be casualties involved as far as the hostages are concerned. This is a situation where the military has to do what needs to be done. “Terrorist negotiations” is basically the upgraded version of civil Muslim appeasement. Action has to be taken now and quickly. It appears that not a single hostage has tried to end the situation, even if it costs him his life.
