But real guns remain permissible. Nevada’s relaxed gun laws, including the ability to carry them openly, have made Las Vegas an attractive spot for shooting ranges and gun shows.
Some observers think police should step up their presence on the Strip, just as they did after three slayings in 2011.
‘‘Clearly they should be looking into this because they have had a string of incidents now, and while they've all been random incidents, they all did happen,’’ said David Schwartz, the Director of the Center for Gaming Research at the University of Nevada, Las Vegas.
On Thursday, police spokesman Jose Hernandez said the department had no plans to send additional officers to the Strip, noting that crime remains relatively low for a town that accommodates so many visitors each day.
But with violent crime, as with so much else in Vegas, perception may outweigh reality. As a place built on the promise of letting loose, the city must work extra hard to banish all fear of danger, said Tony Henthorne, a marketing professor at the William F. Harrah College of Hotel Administration in Las Vegas.
‘‘It’s important for any destination that relies on tourism for a major percentage of its income to appear safe,’’ he said, ‘‘and also actually to be safe.’’
