If your kids want to dress up in gangster Halloween costumes, you should think hard about letting them wear these things to school. Any type of gun is going to get them into trouble, even if it is a toy water gun made to go with a costume. Tell them to save that type of costume for at home. Instead, think of something else for them to wear to school. Some schools pass over costumes each year simply because there are so many different accessories on kids costumes that resemble weapons. Keep that in mind if your kid can dress up and outfit them accordingly.
