Those are almost certainly not "his words". They were more likely wordsmithed by a lawyer or team of lawyers, and paid for by one of the anti-gunner groups.
Some sentences are carefully worded, others are just outright incorrect (lies).
Sort of paraphrased by me, but close to verbatim:
"I had to have a background check before I could join the marine corp and carry a weapon like this...." Did he have to have a background check before joining, or did he have to have a background check to be able to carry that weapon? His statement does not make this distinction clear.
"here at home, anyone can purchase this weapon no questions asked". As we know, that's not true. I bet almost all "new" purchases already require and have NICS checks, The often-quoted figure of %40 acquisitions w/o NICS includes all transfers, gifts from family, inheritance, etc...
This is more misrepresentation of facts, spun to sound like it has some different meaning. Translation- some mis-statements are also known as lies

...at least among the folks I hang out with...
