Time is not on the side of the antigunners.
There is a limited window after an atrocity where they might be able to exploit it for political advantage:
“Manhattan District Attorney Cyrus R. Vance, Jr., Los Angeles City Attorney Mike Feuer, and 25 additional members of Prosecutors Against Gun Violence (PAGV) today announced their strong support for the Automatic Gun Fire Prevention Act introduced by Senator Dianne Feinstein (D-CA), which would ban the sale and possession of accessories used to increase the rate of fire on semi-automatic weapons …”
At this point the media has lost interest and it is reasonable to assume the antis window has closed.
Some people don’t want to accept that:
It's been three weeks since nearly 60 people were slaughtered at a concert. We MUST act. That starts with banning bump-fire stocks.

Whining Congress isn’t taking up your personal political agenda is undignified. It demonstrates weakness and proves lack of public support for the issue.
