The point is that all sky-pointed bullets are NOT going only 170ft/sec.
Yes, it is reasonably established that bullets fired straight up do not regain their initial velocity on the way back down.
But, at less-than-vertical firing angles, they can retain a lot of their initial 4-figure-fps velocity, and how much is very dependent on particular trajectory, wind, bullet composition, and initial angle. Dependent enough that it's specifically outlawed in many states.
So, don't go glibly firing off skyward celebratory shots (over)confident in your understanding of the physics (or implicitly advocating it). You might be willing to take the risk, but no one else is willingly undertaking the risk you are creating.
I honestly can't believe that people would argue that they should be allowed to fire guns up in the air, lmao. You & I both know people don't indicate while driving, so I'm sure we're not that surprised, though.
