Scalia got the history wrong. Here is the Historian's amicus brief (https://www.nraila.org/heller/conamicusbriefs/07-290_amicus_historians.pdf). Here is the NAACP Legal Defense Fund's amicus brief (https://www.nraila.org/heller/conamicusbriefs/07-290_amicus_naacp_ldf.pdf). Disclosure: I helped proofread (but did not write any part of) the NAACP LDF brief.
