That's exactly one of the challenges that we will face if something happens. The issue is not defined until later on. Disinformation being sent to voters about a polling location may be the first sign that a party database has been hacked. From the fact of this information being sent, you don't automatically jump to the conclusion that the database was hacked. In fact, it may be that this disinformation is an error. Is it a disinformation campaign? Is it errors? Was the database hacked? Was it hacked by foreign actors? It takes a lot of intervention to understand a situation.
