It's allowed but don't do it in a provoking way. Terrorism is allowed as long as you don't break rule 20:
Raiding main Government headquarters - such as the Dillimore Department/Aperture Base/FBI Department is not allowed, since it is not realistic. We understand that it is more than possible to do this in real life. However, as this is a county roleplay server, it would be inprobable for this to happen and as such we have decided to prohibate such roleplay.
If you are found inside a government building without authorisation, you will be kicked.
