By 2015, all 30 MLB ballparks must have either handheld or walk-through metal
detectors in place, the league has informed teams.
"This procedure, which results from MLB's continuing work with the Department
of Homeland Security to standardize security practices across the game, will
be in addition to bag checks," said MLB spokesman Michael Teevan.
As the AP notes, the Mariners will have such measures operational in time for
the upcoming season.
As with all such security measures, the challenge is of course striking a
balance between safety and customer convenience, and it will probably take
some time to find that balance
2015年将会全面上路，每个球场都需要有手持的或是步行通过的金属探测仪器
MLB发言人Michael Teevan:这代表人MLB正持续致力于国家的保安
水手队在接下来的球季就会有相关的仪器
