...new tests on the bullets supported his remarkable claim that police framed him with bogus evidence.
Whose bullets were they?
Might not necessarily have a trace on whose they were but they could tell they were not from a gun he handled.
So why did the cops knowingly 'frame him'? Who were they covering for?
Edit: I have to go so instead of playing twenty questions I'll just add something...
Bullet forensics are as accurate as finger prints. If the lands and grooves match there is no doubt. If the lab declared a match falsely, they knew it was a hoax, apparently they 'have been closed' for 'mishandling' evidence? Thats evidence of a far deeper problem connected with the P, not just "whoopsies".

25 years later, likely your questions cannot be answered.
This case demonstrates how poor our criminal justice system is.
Forensic examiners use the marks left on bullets to match them to specific firearms, but the technique lacks a solid base of research, and errors are common.
Forensic examiners measure bullet size to determine caliber, then check the direction of rifling marks and the degree of twist to narrow down the gun's manufacturer. To match a specific firearm to a bullet, investigators test-fire the weapon with a new slug and compare both bullets under a microscope, looking for identical striations. Investigators can also query computer databases that suggest potential matches.
As with fingerprints, not enough research has been done to quantify the probability of error in ballistics matching. So it's impossible to say with certainty that the marks made on bullets as they are fired are truly unique to an individual gun. Currently, ballistics examiners are aided by computer databases such as the ATF's National Integrated Ballistic Information Network, but lab techs always rely on their own visual inspection to make the final call. The Association of Firearm and Tool Mark Examiners only requires an examiner to find "sufficient agreement" between bullets in order to conclude that they came from the same gun. Those judgment calls can cause false results. Last September the Detroit Police Department's crime lab was shut down after an audit by the state of Michigan found a 10 percent error rate in ballistics identification.
One fundamental problem with firearms analysis is the lack of a precisely defined process, the NAS found. An examiner may offer an opinion that a specific tool or firearm was the source of a specific mark when “sufficient agreement” exists in the pattern of two sets of marks, but there is no precise definition for that statement. The NAS also found there have been no scientific studies to answer questions regarding variability, reliability, repeatability, or the number of correlations needed to achieve a given degree of confidence.
