Public safety officials announced plans for stepped up security measures at the 2014 Boston Marathon at a joint press conference with marathon organizers. There will be a significant increase in the public safety presence across the entire route this year but organizers say that they are doing everything they can to maintain the atmosphere of the race.

A bulked-up public safety presence will be particularly noticeable at the start and finish lines of the race, as well as in popular spectator areas.

"We are confident that the overall experience with runners and spectators will not be impacted and all will enjoy a fun, festive, and family-oriented day," said Massachusetts Emergency Management Agency Director Kurt Schwartz.

A stepped-up video surveillance and bag inspection effort is planned for the event. Spectators are strongly discouraged from bringing over the shoulder bags or backpacks to any spot along the 26.2 mile route. Searches at screening points are likely according to officials and could lead to long delays at entry points.

Spectators are advised to bring all their personal items to the racecourse in a clear plastic bag similar to one they would use for passing through airport security screening checkpoints.

An enhanced video surveillance program will be in place along the racecourse. The plan includes the deployment of the portable surveillance cameras that were first used at the 2013 Independence Day celebration on the Boston Esplanade. Private businesses along the course have been contacted about possible involvement in the race coverage. […]
