In the wake of the Las Vegas massacre, some are asking if hotels should increase security to prevent mass shootings.
Jim Hanson, a retired US Army Special Forces soldier and counterterrorism expert, said that's a natural reaction to such a horrific attack, but he doesn't believe it will work
"I don't think you can secure the entire United States of America," Hanson said. "We are one giant soft target."
He pointed out that across the country, people gather en masse at concerts and sporting events and on public transportation systems.
"Every place where you've got more than a couple dozen people, are you going to check the surrounding areas to make sure no one can get to high ground and shoot down on people?" he asked. "That's what the Secret Service has to do to protect the president, and it's a massive undertaking. So I don't know that that's the solution to this problem."
He said the sad reality is that the world is a dangerous place, and we cannot assume that there will be a "magic solution" to death and destruction.
Hanson said one of the most effective ways to prevent attacks like what happened Sunday in Vegas is, "If you see something, say something."
"That's the likely place you can get ahead of this, is the personal angle, someone with knowledge of a potential shooter," he said.
