An $18 million dollar radio system purchased by the Oakland Police Department has been giving static instead of 10-30s in progress, and the interfering party has now been collared - AT&T. Local officials and the FCC told the mobile network that its towers were blocking police communication, particularly when patrol cars were within a quarter-mile of one. However, some local pundits have said the problem is of the PD's own making, claiming it invested in an inferior system and didn't check carefully enough for interference before making the buy.
