Gun Control & RKBA

emocrats were angling for votes on the two gun control measures, which they are presenting as amendments to a pending spending bill, demanding that it was the least the Senate could do to respond to the Orlando massacre that killed 49 last weekend.

What Dems might do if (& presuming) both these efforts fail due to republican obstructionism via the gun lobby, is to create an 'assault weapons ban' for those on a terrorist watch list.
That is to say, if not a total gun ban for them, at least ban those on a terrorist watch list from being able to buy assault rifles such as the sig mcx or the AR15, These both use a low weight 0.223 or the similar nato round which are so light they blunt rifle recoil so as to make shooting more accurate as the rifle needs not be re-aimed as much after firing shots, as do bullets with heavier weight & larger calibers.
These assault rifles using these low weight bullets are 'en vogue' for mass shootings due the same reasons soldiers like them - can carry more bullets, light recoil, & higher accuracy & lethality. At least they wouldn't be able to get assault rifles, while still being able to exercise their (barf) 2nd Amendment rkba.

Also, the nra is fos when saying a ban on all those formerly on a terrorist watch list (as recent orlando shooter) might not be deterred by a ban on those currently on a terrorist watch list. Some 'formerly's' indeed would be deterred, as there would be a 'threat' of being identified as having once been on a terrorist watch list, and this in itself would inhibit many of those people from even desiring to try to purchase a gun, for either an irrational fear of being reported to cops & quickly arrested, or being exposed by the gun dealer to the community he lives in, iow paranoia.
As far as 'law abiding americans' being prohibited from buying a gun if they are accidentally on a terrorist watch list ban, the gun lobby makes the absurd conclusion that all of these people would even want to buy a gun. Most likely would not even want to buy a gun, unless they were truly terroristic of course.
Most all of the rest should not complain severely about being accidentally put on one since they could simply go to sheriff or authority & provide proof that they are legal beagles, and weighing the positive benefits from a terrorist watch list a true citizen should understand. True terrorists generally could not do this.
