Lots of ways to manipulate data and tests. I think I'll wait a while to see how it stands the test of time. Until then, I keep to the old reliable and proven products.
I also wonder if you had the misfortune to actually have to use something like this, what the lawyers would make of it. I can see them arguing that you were using a round that was "boutique" and intended to do "excessive damage" and they could try to work the angle on "premeditation" somehow. Let's face it, in this day and time, people are always looking for an angle to shift the blame. That's why I don't have "zombie killer" stuff.
Not a lawyer, but I also don't underestimate the stupidity/ignorance/conniving of society these days.
