>> Thank you Paul, and thank you Julie for spreading this.
>> There’s a huge rally coming on March 24th. I could foresee an editorial in a leading journal and a talking point that can be broadcast at the rally stating that this country can expect another mass school shooting by November 4, 2018 (170 days, allowing for 2 months of summer vacation).
>> A simple benchmark date like this can focus the discussion in a way that makes the gun lobby defensive, and can be repeated. aThe action points you mention below, (mass shooter drills, focused MH awareness drives early on) also put the momentum towards action and sustaining the principle that this should not be considered normal or acceptable.
>> I am not a writer or authority, but I’d love to hear someone from this group who is and can further mold this into action.
>> One further idea: on March 24th, the day of the rally, I’d love to see ER docs (and nurses and staff) wearing a scrub/shirt supporting the rally. For example: a red top saying “we stand with victims of gun violence” or “no more shootings”
>> … again, the germ of an idea and I’m grateful for this forum to help work it out.
