The 2014 Winter Olympics will be held in Sochi, Russia. There has been a great deal of concern over whether or not this is a safe location. President Vladimir Putin has intensified security measures and wants to ensure athletes and fans feel safe in the country.

Security measures start when guests step off the plane. The airport underwent a $440 million renovation that included adding enhanced cameras. No liquids are allowed on trains that transport people to the venues. The rail link to the Olympic venues passes through police checkpoints at every station. All passengers are taken through metal detectors and searched by security personnel.

The Olympic venues have been put inside of a metaphorical bubble. Every square inch of it is being monitored by police. Approximately 37,000 security personnel will be deployed. This is almost twice the amount that the summer games in London had in 2012.

Ticketholders walk under an array of cameras all equipped with facial recognition software. If they are chosen they are required to step into a full-body scanner. All guests must pass through metal detectors twice and show their documents three times; all before they get beyond the checkpoints and past the armed guards to enter the venue.

Despite all of the precautions, there are still threats being made that could potentially disrupt Putin’s work to assuage people’s fear. An e-mail was sent to the United States and several other European countries warning that there could be a terrorist attack on those attending the Olympics.

“The IOC takes security very seriously and passes on any credible information to the relevant security services,” International Olympic Committee spokeswoman Sandrine Tonge told CNN. But the e-mail received by the national organizations “contains no threat and appears to be a random message from a member of the public” she said.

All countries are still participating as planned. CBS News senior security contributor Michael Morell, a former CIA deputy director, said that he would still attend the Olympics and bring his family but these are the “most dangerous Olympics” that he has ever experienced.

Morell knows that the terrorist group threatening to attack is “capable, dedicated, and determined” and has been around a long time. They have recently attacked twice in Russia and claim they want to attack during the games. Since there are so many security personnel at the games Morell is not concerned with the venues but rather hotels and transportation.

He advises anyone attending to be aware of their surroundings, saying, “If somebody put a package down or a backpack down, I would walk away from it as fast as I could. I’d inform security personnel. I’d also watch people’s behavior and if there was anything concerning, I’d walk away”.
