It is the policy of the Commonwealth to protect and assist citizens in the exercise of their First Amendment rights. All citizens are encouraged to express themselves on issues of importance. The rights of citizens to demonstrate in a peaceful and lawful manner in and around public buildings and grounds owned by the Commonwealth will not be abridged. However, it is recognized that the time, place, and manner, although not the content, of demonstrations may be regulated consistent with other uses of the same facilities.
