When reaching compromises, you must be very careful with how far you compromise. In this case, to "take what we can get" would be to accept a separate permitting process for open carry versus concealed carry where your instructor gets to determine if you can carry openly in addition to being able to carry concealed, or if you can only carry concealed because he happens to agree with the Oklahoma Rifle Association's opposition to open carry (whether independently or because of a gainful relationship).
This makes no sense to me. If one instructor refused to issue the safety and training card for OC, you just find one who will. No one private individual could prevent you from meeting the requirements in the law to OC.
Not that I like the Russell amendment, I like the chances of Rep. Martin's language better. The ONLY problem I have is the 4th amendment issues of stop and check the permit on sight.
