“Let us be clear, the issue was not that they responded, but that they did not advise,” the statement read. “These officers responded to the February 14, 2018 shooting in Parkland, after the shooting was over. They did not advise prior to self-dispatching, during the incident, nor immediately following. They did not advise dispatch, their SWAT leaders or even check-in with the Incident Command in Parkland.”

I can kind of understand this. The situation was over, but they potentially created another situation by entering the premises (I assume with guns?) without telling the proper chain of command they were there. So they potentially created a false alarm and/or another situation.
