What are two examples of how a persons constitutional rights can be limited

1. Right to privacy. The constitutional right to every person 's freedom to privacy is affected in so many ways.  For example, when a person enters any public space, their right to privacy is no longer considered. There are so many cameras in cities and everywhere capturing peoples actions. People with mobile phone cameras are taking pictures and posting the same to social media. These actions greatly limit a person's right to privacy.
2.Right to gun ownership. Its stipulated in the 2nd amendment of every individual right to own a gun, but when this endangers other peoples lives then that right is taken away.
