Oh, yeah...and he knows he’ll go to the pen over this. He’s just hoping to avoid a murder conviction.
Which I think he should.
I don’t know what side you are on in what capacity but discussing a murder case from the inside in any capacity, on a public forum, is ludicrous and dangerous for all involved.
Obviously there are ballistics experts who know this stuff, can examine the actual evidence, and work within professional and legal guidelines.
If you are not one of them, leave it to them and rely on them. Whether for prosecution or for defense.
