Providing an opening for criminals without realizing it

From Bush, Kerry cross paths in Iowa (BBC News: 4 August 2004):

US President George W Bush and his Democratic rival John Kerry have spent the day hunting votes within blocks of each other in the state of Iowa.

Mr Bush met supporters at a rally in the town of Davenport, while Mr Kerry held an economic roundtable discussion with business leaders nearby. …

Political pundits were not the only ones taking advantage of the day’s events.

Three local banks were robbed as the campaigns hit Davenport.

The first robbery occurred just as Mr Bush stepped off his plane, local police say.

The second and third robberies – at different banks – took place while the two candidates were addressing their respective Iowa crowds.
