Editing Jackson Gang (section)

==Activities and conflicts==
On May 21, 1900, Jackson stabbed New York police officer William J. Tynan during an attempted arrest. Contemporary reporting called Jackson a well-known character and documented the violent encounter.<ref>[https://www.nytimes.com/1900/05/22/archives/policeman-tynan-stabbed-humpty-jackson-a-wellknown-character.html “Policeman Tynan Stabbed; ‘Humpty’ Jackson, a Well-Known Character”], ''The New York Times'', May 22, 1900.</ref> This establishes Jackson's activity by 1900 but not the gang's exact founding date.

Lewis associated the neighborhood formation with stickups and street robbery. Asbury additionally attributed burglary, warehouse theft and hired assault to Jackson's group and estimated a substantial roster.<ref name="Asbury" /><ref name="Lewis" /> Those later numerical and organizational details should be treated as narrative estimates rather than a verified membership census.

Asbury described conflict between Jackson's cemetery gathering and men associated with the [[Eastman Gang]], including “Crazy Butch.”<ref name="Asbury" /> Episodic fighting does not establish a permanent alliance system or prove that Jackson was an Eastman subordinate.

“Spanish Louie” is commonly identified with Jackson's circle and with gambling-related protection. His presence illustrates cross-ethnic membership and association. It does not turn the entire gang into a Jewish-American organization or establish a formal lieutenant rank unless a source explicitly does so.
