>> the nation's counting on you. >> two of the main sticking points about gun control are mandatory federal background checks and mental health regulations. and here at home, our weapons laws are toughest in new jersey. they include an assault weapon ban, a firearms registry, and a magazine capacity restriction. you also can't buy any parts to make an assault weapon. pennsylvania does require a permit to carry a firearm, but only in a city with more than one million people. so only philadelphia qualifies. delaware has the most lax gun laws in the state, in the tri-state. it has no magazine capacity restriction and no firearm registry. 5:36. philadelphia police say they plan to learn from the tragedy in las vegas. because the city often hosts big outdoor events, they already have security measures in place. nbc10's katy zachry joins us live from the ben franklin parkway. what are the security measures that police talk about? >> reporter: philadelphia police have detailed for us the security levels that they have in place for every big event the city hosts. many of them happen here along the ben franklin parkway. for those events like the big concerts or the papal visit, here is what they do. they have plain clothes officers in the crowds scanning, looking for any threats. they have s.w.a.t. officers stationed on higher ground. you'll often see police helicopters scanning rooftops. and blowout gates can be opened at a moment's notice to let the flood of people rush out. with these measures and more in place, some people tell us they still don't feel safe at large gatherings. >> i think nowhere is prepared for that type of situation. that's something we shouldn't have to prepare for, i feel like. it's really scary. i have a son, so it's like what did i bring him into, and he won't be able to do a lot of things that i got do when i was younger. i don't want to bring him out. i don't want to be around a group of people. you never know what could happen. >> reporter: this morning we are calling some of the big hotels located in philadelphia to find out if they're changing any of their security practices in light of this deadly shooting. we'll have an update coming up at 6:00. reporting live along the parkway, katy zachry, nbc10 news. philadelphia's ben franklin parkway like the vegas strip is surrounded by highrise hotels. we talked to a hospitality consultant who told us there isn't any way to keep hotel guests from bringing weapons. he says there are other things hotel workers can look for starting with baggage. >> if you have a heavy amount of bags and you're only staying for a few nights and you're by yourself, that for me is the main red flag. >> you don't rely on hotel workers to try and be your eyes and ears for your safety?
