I am in favor of folks testifying at the public hearing. The anti-gun folks will certainly have their testimony times at the public hearing.
Not sure if it still works the same way, but many moons ago I was involved in health insurance legislation open hearings at the Capitol. First went one group (those of testifying in favor of such-and-such bill), and then went the second group (the big wigs from the insurance industry who were against such-and-such bill). Interestingly, when the second group made comments that were flat out lies, and the first group wanted to go back up to the mike and have a chance to say differently, the first group was told that they could not...that the parliamentary procedure did not allow for there to be a debate back and forth at the mike!
So, again, I don't know if it is set up the same way of each "side" having a designated speaking time, or if they would allow for a counter-statement to be made. If it is the latter, then Jay is right on the mney of saving one's quicker thinkers/speaker for the counter remarks.
At that prior time, we had a legislative aid helping us out as to what can and cannot be done. Perhaps one of Senator Christensen's aides would do the same.
