Before or after the troops showed up?
Southern states voted to abolish slavery *after* Troops seized them.
The Maryland state legislature voted massively (53-13) AGAINST secession **before** Confederates formally declared war on the United States.
Once again, *AFTER* the troops showed up and arrested everyone Lincoln's people thought might vote otherwise.
Not how the "will of the people" is supposed to work.
No Marylander -- zero, zip, nada Marylanders -- were arrested before the state legislature voted 53-13 against secession on April 29,1861.
Just one week later, May 6, 1861, the Confederate congress declared war against the United States, making, by definition, any pro-Confederate activities in Maryland a matter of treason.
That's when the arrests started.
