An Army colonel's open letter to morons who videotape shootouts with smartphones

[Moonbeam]

He could have talked about momentum and I wouldn't have said anything. But he said F=ma, which is not momentum.

Well it is when time equals one. But I felt that nonsense was too strong a word to use because he was speaking to a non-technical public who probably can relate to force and violence better than P = mv. F = mv/t = P = mv/1 where t = 1
