Im not really sure of the gun laws but i believe because children are involved and theyre still working things out or "disputing", one can ask for such a thing if they feel threatened. I would assume its only temporary until they come to agreement on custody and/or the "dispute/s" are over. Im sure if Suggs wanted to he could fight it, but its probably better in the courts eye if he just surrendered them. Probably only reason she or her attorneys asked is because of what happened in KC though. Again im not the best source, but to my knowledge its unlawful for them to take your guns, but its not to temporarily cease them.
As part of ongoing domestic disputes involving Ravens linebacker Terrell Suggs and the mother of his two children, Suggs was required last month to surrender several firearms, according to Justin Fenton and Jeff Zriebiec of the Baltimore Sun.
