TULSA, Oklahoma - Thursday, FBI Director James Comey said, right now, there is no credible threat of a Paris-type attack happening in America, but that doesn't mean we should stop paying attention.

The U.S. attorney general said, since 9/11, the government has worked around the clock to ensure American safety.

Since 2013, more than 70 people have been charged with conduct related to foreign and homegrown extremism.

Although there's no evidence of an attack, Oklahoma's Homeland Security Department said we should always pay attention.

The images of the aftermath of the Paris terror attacks are etched into our memory. As a result, the questions on ‘could something like this happen in America,’ continue.

"You have to understand there are always leads coming in, every day, with suspicious activity of someone who is ISIS related or some other type or terror-related information, and they just have to be checked out," said Kim Ed Carter, with the Oklahoma Office of Homeland Security.

Carter said previous terrorist attacks in American - like 9/11 or the Oklahoma City bombing - have helped make America's security operations one of the most sophisticated.

"We have a good operating system for law enforcement here and I think one of those reasons is what happened in April of 1995. We know that it can happen in our state, and our officers believe that and work together very closely," he said.

Despite what's happening in other countries, Carter said Americans shouldn't stop living their lives or going to big events for fear of what could happen; instead, they should be more situationally aware.

He said investigations show that after an attack there are always people who knew or suspected something bad would happen, but never said anything.

"If you see something suspicious, overcome the urge to say ‘I'm afraid to call someone.’ You need to report that suspicious activity. That is about the only way we are going to prevent a lot of these attacks," he said.

If you're planning on going to the big OU game this weekend, sports representatives said there will be security as usual.

They ask you to be aware that it may take a little longer to get through the gates.
