Rob Glenn explains Ohioans should be watching for things that don't add up, including suspicious people eyeing government buildings or infrastructure.
"Somebody that maybe is aggressively trying to enter an event or someplace that you know that they just don't belong," says Glenn.
The head of Ohio's Homeland Security department says his staff has been reviewing security processes gathered over the last decade, adding they have to "look back to move forward."
"And we account for those terrorists arrested in Ohio," says Glenn. "I can tell you with the recent threats that have been communicated and made public, we've been in the know for quite some time, and we've been able to stay ahead of that with our law enforcement partners at the federal, local, and state level."
Glenn points out authorities have investigated terrorist activities that involve the Buckeye State. He says there's no particular threat that Ohioans should worry about, but he urges everyone to report any suspicious activities to police.
