Comm2A does not take a political position on issues; we take legal positions.
We are realists and bring cases where we (a) believe the law is on our side, and (b) believe we have a reasonable chances of prevailing in court. We also sometimes get sucked into cases we never would have brought. For example, we would have never used the case of a 14 year old urban minority youth carrying an illegal handgun as the basis for a case contesting the unsealing of juvenile records, but we none the less participated in Chardin since someone else initiated the case. Note that we lost Chardin - something that our case analysis would have predicted as a serious risk given the nature of the offense and, as such, if it was our call, we would have waited for a more sympathetic plaintiff.
As to felons - it is possible we could encounter a case of a non-violent felon that is worth bringing, however, the comment about felons in Heller could make that difficult. Also, there are felonies that are not felonies for the purposes of 18USC922g. If you know of anyone who was denied a LTC due to a conviction under the Sherman-Clayton anti-trust act, let Comm2A know.
MA has misdafelonies (misdemeanors punishible by 2.5 years which exceeds the 2 year threshold to be a felony according to 18USC922g, including first offense OUI. We definitely do not concur with the conclusion that this should bring a state and federal lifetime prohibition, and it's on our radar screen.
The machine gun prohibition is even more problematic. We don't see any chance a MA court would over-rule the denial of a MG license on the basis of "because they are too dangerous" (the Framingham PD policy), so we probably won't be bringing a licensing appeal. Likewise, the chances of winning a federal case, given the limitations specifically called forth in Heller, as slim to none, so don't expect one of those from us.
So, it is not so much the "position" of Comm2A, but the result of "potential success/failure analysis" that drives the decisions on the cases we bring.
