Here is the entire weapons policy:
It is the policy of Anime Los Angeles that no real or realistic projectile weapons may be carried anywhere within the convention except during the masquerade or specially approved events. The use of a weapon during the Masquerade or during a programming event must be approved by the Masquerade Director or the Programming Coordinator respectively. No weapon of any kind may be drawn or wielded in any area of the hotel or convention space.
Anime Los Angeles defines a weapon as any object designed to cause damage, or any replica of such an object, or any object that the Committee determines to pose a risk to the safety of others or to personal or hotel property. The Committee reserves the right to alter or amend this definition and the right to impound weapons for the duration of Anime Los Angeles. Failure to surrender a weapon for impounding is grounds for immediate revocation of membership without refund and expulsion from the convention.
Dealers who sell weapons must securely wrap each item at the point of sale and provide each customer with a printed copy of these rules.
We at Anime Los Angeles know that most people who would like to carry weapons are sensible and careful individuals. However, we must keep in mind liability, legal issues and our relationship with the hotel. The safety of you, the members, must outweigh any other consideration and it is with this in mind that these policies have been formed.
So imitation blades are probably OK, but you can't wave them around.
