"Each person’s vote in the 2013 election takes up about 27½ inches of the electronic machine’s paper trail. Each roll from the 2014 election is 385 feet long, and stored in 42 boxes that are not segregated by precinct or voting district."
Definitely not as easy as making a photo copy. Maybe they could let her pay to hire someone to sort through, find the right roll (without damaging anything), then carefully unroll and photograph it for later study before re-rolling it?
One issue of course would be that the voting registry (which is public already and contains who voted and is time stamped, so also in what order) could very easily be used to guesstimate matching up specific people with specific votes, as the roll is going to be in chronological order as well. I'm not totally familiar with Kansas law, but there's a good chance they're legally supposed to have a secret ballot.
