The person who successfully stole petitions:

Thanks for the info.

But I'm not sure I would consider it a complete success. It looks to me like he stole them then people surrounded him and forced him to give them back a minute later.

At the point when he was confronted, had he already stolen the petitions. The fact that he gave them back doesn't turn that successful theft into a mere 'attempt'. It doesn't matter whether he was confronted a minute later or an hour later.
