excue excues me. let's bring in former fbi agent, steve gomez. ny of them are very young? >> yes, in this situation when you are in a venue or a stadium, in such as this one. 21,000 people. the stampede. potential for stampede is in and of itself a danger to the people that are there. i mean there is a lot of risk that is involved in, in a stampede such as what we are seeing here. so, i think the announcement was very good in the sense that they're trying to, get everyone to remain calm. and to move slowly. now, the fact is, inside the stadium, there was no threat. now, everybody didn't know that. they just heard hey boom. they didn't know where it came from. but, it, if you are, not faced with, a threat right in front of you. if there wasn't a gunman inside the stadium. wasn't, what looked like a device that had gone off inside.

reason to run out of there. with that many people creating a stampede injuring each other and now you have a problem there. so, i think it was a good announcement. have to consider when you are going to these events, i told this to my daughter. when you have this situation, you have to calm down and tripe to think, do i need new run out of there? right away. or do i need to man hold back. let the crowd kind of move slowly and then, walk out of there when it is safe. >> steve, how do you make that call? >> you have to think about what is facing you. what is in front of you? and we say, run hide, fight. that's the, the -- basically the slogan that has been put out by dhs for, for any body encountering a terrorist attack or active shooter. run, hide, fight. means if you have something you are facing that is either an active shooter or some type of terrorist situation. you need to run out of there. if you can't then you need to hide.

to fight. and the fact is, in that situation, they heard a boom. they didn't know what was going on. there was no real threat that was in front of them. unfortunately, the threat was outside of the stadium. and the people that were out there, they're the ones that were injured. so if you are inside. and you don't see anything in front of you. the panic in and of itself became a danger for all of the people. now, we haven't heard if any have been hurt from the stampede. but, they just have to consider that, that, you know, know your surroundings, know where you are. think about where the threat is. and in this situation, it was outside of the stadium. >> all right. such a horrible situation. no matter which way you look at it. for, many of those kids over there. steve gomez. thank you. the morning's other major stories next. including a busy day ahead for the president overseas. as his controversial budget plan is released back here hat home in the u.s. >> first, a look at today's temperatures.
