Really wish we knew the cal.It could give people an idea what to watch for.
One thing I'd watch for would be drivers or passengers wearing plugs or "earphones" in cars.
There are far too many survivors who would hopefully remember the color/make/presence or absence of other vehicles beside them whe they heard the thunk of the bullet hit.
Although it might add to their sick thrills, there is a very real possibility an adjacent driver, if hit, would swerve into their vehicle.
A malvo-type vehicle rigged as a blind could be part of the scenario, but would be most likely parked, on an overpass, aproach ramp, or frontage road, above road level. Without information on terminal trajectories (where the round went after it hit) it is difficult to do anything but speculate.
The direction of the bullet after the initial impact would tell at least some of where to look for the shooter(s), allowing to tell relative elevation, whether they were shooting toward the aproaching vehicle, side-on, or as it was traveling away.
Remember the lady who was killed in the passenger seat. The door entry hole was low and forward, it missed the driver and killed the passenger. This may indicate an upward traveling bullet based on the trajectory.
A gun could be rigged sideways in a trunk for example to fire through an aperature, similar to the way M&M fired from their trunk. The trunk acts as a sound suppressor. The driver doesn't need to wear earplugs, he just yanks a string or pushes a button.
Just a thought.
I don't think so...
How would they see it unless the shooter was holding the handgun/rifle anyway?
If someone was holding a gun and aiming it, I'd think someone would sure notice that - wihout being told by the police/media what caliber bullet was used in previous shootings.
Unfortuntely, reavealing the caliber of the bullet would also tell a copycat what caliber to use - if they said (for instance) it was a .223, and shootings start up somewhere else, how would the police know if it was the same shooter or a copycat?
Also what if they said (for instance) it was a .223 - would that mean that anyone who knew of someone who owned an AR-15 / Ruger Mini-14 should call them in to the police as a suspect? Should sales of the caliber ammo being used in the shootings be suspended?
I don't think there is any benefit to letting out the caliber of bullet being fired at this point.
