Nah sorry I think he shoulders some of the blame, people were screaming at him that there were people dying in the crowd. He could see ambulances and chose to do nothing. Him and Kylie Jenner should save their false tears cause no one believes them. There have been a few videos circulating of other performers stopping their concerts for far less after finding out their audience was in danger.
as a fan I can admit he should shoulder some blame for exacerbating things (telling people to jump gates, mainly), but:
1. it is very normal for people to be passing out/injured at festivals and shows. crowd compaction of some form is pretty normal now and a lot of that is down to a culture of people wanting to squeeze to the front for the 'best' experience not realising it causes issues for others. this has been compounded by the fact that promoters have just let it slide for years, pack more people in and cut corners from stage design to hiring people. the normalisation of this is what leads to recklessness - artists assume it's manageable now by those that are hired (security, medics etc). the event should've just been stopped by the police or the named Live Nation individuals who have the 'power' to do so - and that probably should've been a lot earlier.
2. that 'ambulance' from accounts of those there was a security vehicle and again is pretty normal in a US festival in my experience for that to be deployed into a crowd. shitty behaviour jumping on it no doubt though.
3. he stopped the show a few times in fairness - and i've been to shows of his in the past where he's stopped for injuries etc too. again, not excusing that he might exacerbate things, but you see people pass out from compaction at other gigs too, even with more 'calm' music.
i know people hate the kardashians/jenners and i'm no fan myself. i don't believe travis is quite as heartless as some are demonising him to be. his apology video was awkward but no doubt his lawyers are in his ears telling him not to say certain things.
