You decide to bring up the camera footage from the first bank, but the moment Jackson sees you pulling the tape back out, he shouts

“OBJECTION!” Everyone gasps, as you haven't even been talking yet. “Really? You're bringing the last bank's security footage back out? Not only would that be useless to the new case, but some new information has come to light for even me! Apparently, Saul is the CO-FOUNDER of Shinging Eye Security! Meaning Saul over there would have had full knowledge of the system, full clearance, and no proper alibi! Humble jury, is this not enough alone to charge Saul with the crimes of now both robberies!

If you are not convinced, may I even give you a motive? My client, Walter Styliac is the other co-founder of Shining Eye Security! At the time of the companies creation, Saul took a deal to sign off the publicity of Shining Eye’s creation for a slight pay rise, but after watching the fame go all to Walter, Saul realized he had contractually signed himself to the shadow, never to get any attention. After too long, he finally broke, and started robbing banks protected by his own security, to point out the flaws and get back at his once friend. I rest my case.”

The whole room gasps, you included. You screwed up, and there is no getting out of this.
