Dan Patrick, the Lieutenant Governor of Texas, has suggested redesigning schools could be the answer to stop the United States' school shooting epidemic.

"We may have to look at the design of our schools moving forward and retrofitting schools that are already built. There are too many entrances and too many exits," he said on Friday (local time).

His comments come after 10 people were shot dead at a school in Santa Fe, Texas.

Mr Patrick, a Republican, said there simply isn't enough security to guard all the entrances.

"Maybe we need to look at limiting the entrances and exits into our schools so that we can have law enforcement looking at the people who are coming."

After the Parkland massacre in February, US President Donald Trump proposed that teachers be allowed to carry guns, but has yet to move forward with the proposal.

Gun-toting support

A man wearing a 'Make America Great Again' showed up outside the scene in Santa Fe, armed with a pistol, not long after the shooting.

He told local TV reporters he was there to offer support, but was immediately stopped by police once it was clear he had a pistol clipped to his shorts.

According to the man, what the victims needed now was prayers.

A bystander told local TV station KHOU he hoped the gun-toting man would get arrested, calling him an embarrassment.

"I have guns...but this idiot is walking down here saying 'Make America Great Again', that's not what America needs. America needs prayers; we don't need this crap," he told reporters.

The latest school shooting is the 22nd in the US already this year.
