In the USA a Mass shooting is considered to be where 4 or more victims are injured or killed excluding the subject/suspect/perpetrator at one location.

So the Cincinnati Cameo nightclub shooting brings to 4 the Mass Shootings in the USA on Thursday, Friday, Saturday and now Sunday, the others being...Knoxville, Tennessee 4 shot 0 dead including a 15 year old struck by a stray bullet sitting in his apartment,  Saint Louis, Missouri  7 shot 1 dead and Fresno, California 4 shot 1 dead.

In the rest of Ohio over the previous 72 hours there were another 18 reported shooting incidents with 6 dead and 15 wounded...a lot more dead and about the same number of wounded as at the nightclub!

In the same 72 hour span shootings in the USA where 2 and 3 individuals were wounded or killed were well into double digits...but less than 4 is not a mass shooting.

I don't believe any of them were considered terrorist acts...mostly just Americans shooting each other!
