Many police departments still use DNA evidence the way they have used fingerprints and tire tracks: to determine whether a suspect committed the crime.

A 'Globe' examination found that Boston police officers exercise broad discretion when deciding whether to issue a ticket.

There was insufficient evidence that Mr. Simmons committed a crime.

The state said this case is not about scientific evidence because they don't have any ... no DNA, no fingerprints. Senator Williams and his gang were out for drugs and didn't care who got in their way. There's no testimony that Washington got those drugs.

The police met with our group and they said crime and drug dealing is way down. It's unbelievable.

We are not supposed to go out and kill all those we suspect to have committed a crime.
