When the cuban problem occured,Roy was panicking alright,but during the panic attacks he killed an innocent person by mistake.I think that if,for example,the cubans came down to NY and Roy knew the identities of the assasins,they would've kissed their own butts.The problem was that the killers were unkown.So thats why Roy got the idea to shoot every cuban that got near him.Also Roy was panicking because his own crime family was goin down on him for the stupid bitch move made by Chris.Now,that dude was a coward alright.He killed people during a deal.
