Gainesville Police Department Public Information Officer Cpl. Tscharna Senn declined to detail plans to patrol the event, but said that the department was "taking this very seriously."
"We are very concerned for everyone's safety," said Senn. "However, we have planned and believe that we have a very adequate plan in place to keep [the people of Gainesville] safe."
The estimated cost of the extra security planned for Jones' event was "tens of thousands of dollars," according to Gainesville City Manager Russ Blackburn. Blackburn said he'd "send Pastor Jones the bill."
"We want him to at least be aware of the cost incurred because of his actions," he said.
There also may be early signs of copycats. According to The Associated Press, a Springfield, Tenn., minister said he also plans to burn a Koran on Saturday, saying he thought Jones was "doing the right thing."
