The only way to defend the Hirohito monument,, is to say that in the larger sense, that the totality of the event was Hirohito surrendering (via a representative).
And by that standard,, Revere’s ride, and the resistance that night, all combined to indeed let the English know that they could not take our weapons.
Revere was captured which is when he warned the Regulars(British)that the colonists was fight to retain their arms. There was no "standard" to adhere too. Sarah was 100% correct and anyone who doubts her words are the ones in the wrong.
