The FBI director says he doesn’t think they could’ve done anything different to prevent the Orlando mass shooting. But I think this gun store owner would disagree:

FOX NEWS ALERT: Gun shop owner reported Orlando terrorist after he tried to buy body armor https://t.co/aiAB4d0cYA

DAILY MAIL – A gun store owner reported Orlando shooter Omar Mateen to authorities weeks before he committed the worst mass shooting in US history.

Robbie Abell, co-owner of Lotus Gunworks, told the Wall Street Journal Mateen came into the store in South Florida in May and asked for heavy-duty body armor like the kind used by law enforcement.

Staff at the store, which does not sell body armor, felt it was a strange demand.

After his request was denied, Mateen asked to buy bulk ammunition.

Though Lotus does sell ammunition, staff shut down his request and refused to sell him anything else.

They subsequently reported the incident to the FBI, Abell said.

The store’s owner Robbie Abell told the Journal: ‘The questions he was asking were not the normal questions a normal person would be asking…He just seemed very odd.’

Abell also said Mateen was speaking to someone on the phone in Arabic and was walking around the store texting.

He added that staff were on high alert since authorities has recently warned them to look out for suspicious activity in the area.

Port St Lucie police said they did not receive a report about Mateen’s suspicious behavior.

The FBI has yet to comment.
