Stumbled on this reddit thread that answered a question I'd had myself but never actually looked into.

Looking for primary source on Lucy Parsons quote: “Let every dirty, lousy tramp arm himself with a revolver or a knife, and lay in wait on the steps of the palaces of the rich and stab or shoot the owners as they come out.” - r/Anarchism

Citizen [Albert] Parsons then read some resolutions of sympathy with the Lemont strikers denouncing the militia, etc., after which the conclave went into secret session for the transaction of private business. There were three women present last night.
