    I'm sorry but this just makes me sad.He and all his gadgets are very impressive, impeccable, etc. But so much manpower, time, and money, into figuring out exactly how gun violence happened. After somebody is already dead. I'm so sad that adapting to gun violence is our reality.

  • Reply Chasmodius February 14, 2020 at 6:47 pm

    I'm a little annoyed that he's talking about bullet trajectory, specifically in a case involving a distance of 800 ft., and he doesn't mention actual ballistic trajectories or parabolic arcs at all! Bullets don't travel in a straight line, which he knows full well. For short-range stuff, I'm sure it doesn't matter much, but for anything over 50 or 100 yards, how do they estimate for bullet drop without knowing the speed of the projectile?

  • Reply jonavuka February 14, 2020 at 11:25 pm

    cant i just use my time machine and get the trajectory of the bullet as it happens?

  • Reply Noelle-Spades February 15, 2020 at 12:53 am

    I'd love to see this guy react to the crime scenes in Detroit: Become Human, I wonder what he'd have to say about the dialogue, technologies and techniques of the characters. It'd be great if he could play it, more specifically, the crime scene where the victim stabbed 28 times. I'm super curious about his reaction.
