What to do? Well, here are a few things I've done so far:
1. Called the NRA, JPFO, GOA, and VCDL, and asked them what they are doing to help Bushmaster in the press to counter the publicity that the Brady Center is gaining.
2. Mentioned to the above organizations that word on the street is that the Brady Center isn't after compensation for the victims as destroying Bushmaster financially thru litigation.
3. Requesting the above organizations contact Bushmaster to advise on how Bushmaster can set up a Legal Defense Fund.
4. Post the Support Bushmaster petition in plenty of places for others to see.
5. I emailed my "Why I support Bushmaster" essay out in an email to my friends and family (if you want to do the same, you have my permission).
Other things you can do? Call Bushmaster and express your support. If you're REALLY motivated, get somebody to print up "we support Bushmaster" bumper stickers and stick them on your cars. Write the major firearms manufacturers and ask them why they haven't formed a trade association to guard them against these BS lawsuits, similar to how the music industry has the RIAA.
I've seen some forums where folks moan about the NRA not protecting our interests. Remember that it is OUR NRA, nobody else's. If you are an NRA member, call them and let them know what you want them to do. If they do XYZ, and we don't let them that we don't like it, how are they to know better?
