After watching every movie, documentary, and videos on 2pac and biggie, i have a theory on what happened. When 2pac got shot in new york, he felt like he was set up by biggie bcuz prior to that incident, biggie had mentioned to 2pac about this “bad guy” that biggie knew who was bad news and told 2pac to stay away from him. this “bad guy” was one of the men who shot 2pac in new york, so 2pac felt like biggie knew what happened, thus feeling like he was set up by biggie and this started the huge fued… 2pac always hung out and was affiliated with gangs in LA such as the bloods so he obviously had enemies even though 2pac never claimed to be a gang member. In las vegas, 2pac and his friends (suge knight, etc…) beat up a LA crip member, so obviously the crips were going to retaliate, especially on 2pac since he was well known, thus the shooting in las vegas… biggie smalls didnt have anything to do with the las vegas shooting but im pretty sure friends and ppl close to 2pac might have thought other wise so in retaliation they murdered biggie in their home city of LA… Suge knight pretty much ran streets in LA during this time, he had the most money, the most power, and everyone feared him, LAPD was known for corruptions, so im pretty sure suge hired a active or former corrupt cop to murder biggie…
