Question

which gang activity leads to legal consequences?
dropping out of college
assaulting people with or without deadly force
missing less than half an entire school year
disobeying caregivers and hanging out past curfew

Explanation:

袭击他人（无论是否使用致命武力）属于违法行为，会导致法律后果。而辍学、一学年内缺课少于一半、不服从照顾者并在宵禁后外出，这些行为通常不属于直接导致法律后果的严重违法犯罪行为（当然具体情况可能因地区法律细节有一定差异，但相比之下袭击他人的违法性更明确和严重）。

Answer:

assaulting people with or without deadly force
