EAST RUTHERFORD, NJ (WCBS 880) - Heading to the Jets game on Sunday or the Giants game on Monday? Pack some patience along with your team spirit.

WCBS 880′s Peter Haskell On The Story

The tighter security comes after Dallas Cowboys fan Leroy McKelvey was charged with sneaking a stun gun into MetLife Stadium on Sunday— and using it in an upper-deck fight — on the 10th anniversary of 9/11.

McKelvey of Moncks Corner, S.C., was charged with three counts of aggravated assault and two weapons counts. He claimed he used the weapon in self defense.

Although the security pat downs at MetLife Stadium are thorough, stadium security expert Stacey Hall said she is not surprised McKelvey was able to sneak in a stun gun.

“I think fans can be very creative in getting prohibited items into venues,” she told WCBS 880 reporter Peter Haskell.

Still, she says, fans should feel safe.

“There is a lot of planning and preparedness that goes into all NFL games,” she said.
