Terror watch list would not have stopped the San Bernadino and Orlando attackers from getting a gun

Steve Berman:

Using the terror watchlist for gun checks is a really dumb idea for several reasons.

The watchlist, as a means of gun control, is set up to fail in the first place, and in cases where guns have been the main weapon used in terror organization-inspired attacks (the government calls them “lone wolf” attacks), the system has a dismal record in preventing weapons from getting into terrorist hands.

(Due to the classified nature of the database, we will likely never know how effective it has been, but going by the last few years in the news, it’s an abject failure.)

Part of the reason for that failure is due to the mission of the organization which created and maintains it.

The FBI operates an office called the Terrorist Screening Center. It’s a multi-agency organization created by President George W. Bush in 2003 to maintain a consolidated database for realtime cooperation and intelligence sharing.
...
The TSC will not confirm or deny anyone’s presence in the database, because that would compromise its mission.
...

There is much more.

In the San Bernardino case the terrorist got the weapons from a friend who bought them for them.  In the Orlando case, the guy was working as a security guard for a company with contracts with DHS and the State Department.  The FBI had interviewed him in the past and dropped the inquiry.

Then there is this:

72 DHS Employees on Terrorist Watch List

Is this their way of keeping a close watch on them?
