The robbery and murder of PNB Rock in Los Angeles has started a lot of conversations within the rap community...

People like Fat Joe say the incident changed his life and he is truly saddened by the murder; while others discuss hood politics, and "checking-in."

In a recent interview with the Nothin 2 Somethin Podcast, Big U spoke on the recent murders, as well as the rules that apply to "checking-in."

According to U, he says he checks-in everywhere he goes; Chicago, Atlanta and so forth, and says that it's a normal thing to do.

The L.A. OG goes on to say that everyone checks-in at some point, even the toughest of the toughest gang members, and it's really about respect at the end of the day.
