To write is to act.

Explanation

A writing carries the force of an act — a treasonous letter is as much an overt act as a treasonous deed.

Where this applies

• Someone wrote a treasonous letter and claims it wasn't an act because they didn't do anything physical.
• Writing something down IS an act — a written threat carries the same force as a spoken one.
• Documents and writings constitute legal acts, not just physical deeds.
