Jay Z is referring to the 4th Amendment which is known as,"Arrests and searches privacy based on probable cause." Meaning that If Beyonce favorites another guys tweet again he will search her IPhone due to the curiosity he is experiencing.Sorry Queen B!

 Kim Kardashian and Ray J are both following the 5th Amendment,which is also known as,"The right to remain silent." Kim and Ray J don't want Kanye West to find out because he will most likely be very upset about it and write a song about it. For example,“Eat breakfast at Gucci,” Kanye raps. “My girl a superstar all from a home movie.”
