Beware of what you wish for. At least there is no statute of limitations for first degree/2nd degree murder until the NY DAs eviscerate the laws.
However, what about rape, kidnapping, armed robbery, child molesting (they are still arresting people for things they allegedly did decades ago), etc?
And if there is an open warrant/case, then the DAs/prosecutors can look at them for that person and see if they have any fingerprints that they can use, any DNA samples they can use for other cases, and the MO of the suspect if they are suspects in a series of crimes or as a serial crime perpetrator.
Remember, there are “Cold Case” openings all the time due to the newer developments in DNA evidence evaluation. Your DNA never changes during your life unless there is some type of radiation/chemical event and I suspect that is very rare.
You’d be amazed at what you can find in old case files. I am constantly looking at them for civil cases, and in one instance, I went back to a 1929 Supreme Court case records about an 1856 treaty the US had with the Indians, and then went back to a book which had an item in it from 1820.
Old records (and warrants are records) should be purged for minor criminal offenses, but the more serious felonies need to stay accessible until the suspect is found to be dead or would be of an age to have died.
New York is corrupt as hell but I wonder if the US Government can impound state records relating to illegals on federal law enforcement grounds re law enforcement.
Time to play hardball with the State politically corrupt DAs, and make them play without a “cup”.
I would not suppose that any warrants for the 7 major felonies would be dismissed.
