If you where a juror.......a cop says he chased a kid .he says ha saw the kid run p a trash can....?

later on an special unit finds a gun in the trash can the cop says he saw the kid run by...when asked if he ever seen the kid actually possess the weapon he asnwers no he did not..the kids fingerprints are not on the gun either.....what do you say guilty or not guilty..remember that the D.A. most prove that he had that gun beyond a reasonable dought...note it was dark.....and the kid has a prior felon for possiesion of a weapon..
