As a UW alum, Husky Band Alum and frequent visitor to campus and athletic events I carry concealed on campus. I have carried OC while leaving an event and walking across campus.
If someone would take the Universities to court, like they just did in OR, I am pretty sure the outcome would be the same. (OR Appeals court just invalidated the Oregon University Systems ban.
The WACs prohibiting carry only apply to students at WSU, but not so at UW. The UW also prohibits staff and the general public. IMHO these WACs are flaunting the law and are invalid. I think we just need someone to test the system to get them removed.
WSU has a slightly different WAC then UW. In the UW WAC the prohibition includes staff as well as students. Can they charge and jail you? No, but they can do anything else that is "administrative" up to, and including, kicking you out of school and holding your transcripts though.
WSU's WAC pertaining to firearms is 504.26.213
UW's WAC pertaining to firearms is 478.120.020 (students) and 478.124.020 (everyone else) IMHO: 478.124.020 could very easily be challanged in court and won.
Both Universities claim authority through RCW 28B, specifically RCW 28b.30.150 (WSU) and RCW 28b.20.130 (WSU)
