Read the passage about protesting.

Alexander is upset about a policy recently enacted by his state government. He talks with several friends who share his concerns, and they decide to take action. They organize a rally at the state capitol. They make signs with strongly worded slogans to get their point across to lawmakers. At the rally, they use a megaphone to share their thoughts with the crowd.

Alexander and his friends are able to do this without the threat of government interference because of which right?
