+Support For the riot shield
Yes a riot shield doesn't shoot bullets it blocks them but however Ci still would be attacked for breaking "Rules"
Quote from the Motd
"SCP-912 may attempt to arrest rule breakers and bring them to GENSEC or MTF personnel."
Ci raiding the site I would say is breaking the rules because only FOUNDATION personal is allowed into the site
and ci doesn't work for the foundation and if they don't work for the foundation they are Trespassing or Invading
Long story short: +Support for the riot shield however ci would still be attacked due to the MOTD
