V Nox, the law library at the County Government Center is very accommodating and helpful. Just don't bring a knife within, it is part of the Hall of Justice, which has "no weapons"signs and metal detectors.

I have carried any number of folders in my pockets ("concealed." as it were) and occasionally a fixed blade on my belt with no hassles from the constabulary. This includes working at the Gov't Center. My boss agreed that my Wave was a tool, not a weapon.
