Many ballistics experts have given testimony in court that a projectile recovered from a crime scene came from a specific firearm -- conclusively and without a doubt.
The MD Supreme Court now requires a higher standard, meaning a ballistics expert is only allowed to state with confidence that a projectile is consistent or inconsistent with projectiles fired from a particular firearm. This means a judge or jury can weigh ballistics evidence and the opinions of ballistics experts with at least some degree of uncertainty.
I worked for 20 or so years in a field where I had to back up my
designs or opinions. They were always challenged,
as I challenged others. To be an expert you can defend
your position with other experts.sometimes you lose.
if you are good you don't lose very often.
Unless there is a political or
emotional factor involved.
Lawyers are political and emotional animals.
Were I on a jury I would ignore an "Expert"
without evidence of a peer review.
