United Press International
MIAMI — Police are readying a
strike force of two dozen anti
terrorist experts in the event of pos
sible trouble at the Orange Bowl
during Sunday’s Super Bowl football
game.
“The threat is there; you have the
potential, said Capt. Mike Cos
grove, who heads the strike force.
“The whole point of terrorism is
publicity. A disruption of the Super
Bowl would be a big plus for any of
the terrorist groups.
The team is undergoing intensive
training this week in sniper and
bomb detection, hostage negotia
tion, kidnapping prevention, dignit
ary protection and demonstration
control.
As for arms and equipment, Cos
grove said the group — composed
mostly of members of the depart
ment’s SWAT team he commands
— will have “everything — the
whole nine yards.
“You’re looking at semiautomatic
weapons, rappelling devices,
helicopters, 130-foot ropes, person
nel in SWAT ready-response uni
forms, the whole thing,” Cosgrove
said.
The team will consist of about 10
plain-clothes intelligence officers
trained to recognize terrorists who
will filter through the crowd and
another 10 to 15 members who will
station themselves near danger
spots, including the playing field.
In addition, he said, a hostage
negotiation team will be at the
stadium and a helicopter will be
“stashed away within seconds of the
Orange Bowl ’’
The anti-terrorist team will not
concern itself with routine police
matters such as drunks and fights,
he said, leaving those to the 130 uni
formed policemen who will be at the
bowl.
