An expert witness for plaintiffs seeking to bar Georgia's touchscreen voting machines showed a crowded courtroom how he could tamper with election results.

From the Atlanta Journal Constitution Politics News:

U.S. District Judge Amy Totenberg listens as Alex Halderman, a University of Michigan computer science professor, shows how a voting machine could be hacked during a 2018 hearing. Halderman gave a similar demonstration Thursday in a trial before Totenberg to determine whether Georgias voting system is vulnerable to manipulation or programming errors.
