Sporting Events- fast forward to November assume the virus in the usa has not reared its ugly head again ....you own the Dallas Mavericks for example and lease the american airlines center....how do you get fans in seats...are asymptomatic fans still carriers ? how do you instill confidence in fan base that your event is relatively safe ...moreover how would you protect yourself from lawsuits if a fan contracts the virus at your event....shouldnt the major sports leagues be at the forefront of partnering with rapid test kits? Will they lead the way?

Second ? FDA Authorization for At Home Kits- I am confused. Can someone share a link to their stance on this at this time . TIA
