I was there. Just a couple rows back from the anti brigade (side note: she really does look like a witch). First, I was baffled by the testimony of the proponents. Initially, the bill was introduced by the author who read some stereotypical e-mail from someone who was a little dramatic in their depiction of what would happen if their rights were taken away. Then she left to go talk to some school kids at the Ordway (WTF!!??). This left Heather in charge to run the show to describe and promote the bill. Interestingly, the first thing that happened with that was Paymar slapping her for speaking out of turn and acting like she was going to run things.

Fortunately she is neither organized nor persuasive in her presentation. Their entire argument centered on "nobody needs these assault weapons" and "think of the kids". They didn't talk at all about the content of the bill or the rationale behind the details within. The FBI guy/private dick was also less than persuasive. He also could not (or refused) to answer any questions posed to him by Cornish or others.
The opponents (our guys) did a great job. The key points were hit: These firearms are used by millions of people. They are used for hunting. There are reasons for their design that are not just "for killing kids faster" (to paraphrase the antis). DPMS rep spoke about the impact to their business if this were passed. They would go out of business instantly. Andrew and Rob's presentation of the 'nice' and 'evil' 10/22s was spectacular. Spot on for what was needed. I thought a bunch of the reps were going to pee themselves when there was mention of actual firearms being in the room. (By the way guys, great job on not sweeping anyone and presenting in a very professional manner.) The father who talked about his kid being shot but still liking guns and why they should not be taken away was moving. We really pissed off the committee with our clapping for these portions. Cornish had to tell us we should stop.

Great points were made such as that this bill would impose severe restrictions on semi auto firearms that are not even done today for full auto class III weapons - annual renewal, background re-checks, fees, in-home inspection, restrictions on where they could be possessed.
We have some reps on this committee that are definitely skeptical of the bills. Newberger and Uglem come to mind. Cornish, obviously. Plus a lady on the right I couldn't see the nameplate for. Interestingly, I didn't hear any reps, other than the author, taking a strong pro stand about the bill or asking questions of the opponents. My first hope is that there is so little support for the bill that it just goes nowhere. Barring that, the other hope is that it is so irrational and inconsistent with other laws & practices that it gets poked full of holes.
Finally, and this is not a new revelation to me but it was reinforced today, antis are a special breed of people. People who work hard to take something away from other people have a very unique mindset and a way of justifying their actions almost solely based on emotion instead of fact. I've seen this in other areas of society as well. Those 'for' keeping these guns legal have facts, logic, reasons, and emotion. The antis have groundless facts and a ton of emotion. They seriously need a good hobby to redirect their nervous energy. Perhaps they could take up shooting sports.
