There still "hasn't been an official briefing or press conference from the Capitol Police since the attack." ( @alexi )

Remember, law enforcement briefings are *routine* for far smaller security breaches and investigations.

Law enforcement briefings are *supposed* to provide transparency, deterrence against would-be offenders, and public safety information that can be vital when a crime or plot may pose future risk.

A reminder of the obvious:

Even if Donald Trump were *not* involved in encouraging the criminal rioters, *any* massive, deadly breach of the U.S. Capitol would still be one of the greatest homeland security failings of any modern administration.

Almost a week later, much of the Trump administration security leadership remains often M.I.A. -- people in charge of homeland security are literally resigning rather than holding public safety briefings.

A full investigation of the government approach to the insurrection must tackle:

The failures in preparation;

The response on Wednesday;

*and*

the continuing scandal of (large parts) of the Trump administration sitting out even a pretense of taking the response seriously now
