A bulletproof jacket is worn to protect the torso from small-arms fire and light shrapnel from explosive devices. These jackets are consisting of many layers of fine and compacted woven fabric that absorbs the effect from high-speed projectiles. Bulletproof jackets can be accommodated with ceramic or metallic plates that are designed to protect the body from rifle fire or larger projectiles.
These jackets are often worn by the soldiers, military, law enforcement officials, and swat/police teams in situations where any suspicious firearm or other destructive device is found. Also, Private Citizens, such as VIPs, hunters, gun store owners use them for their protection.
Body armor has proven that it dramatically decreases the wearer’s chances of death. And this is the valid reason that has led lawmakers to regulate the purchase of bulletproof jackets so that criminals do not get the protection it provides. In many countries, there are many restrictions on the purchase of a bulletproof jacket that include laws on how a vest may be purchased and by whom.
Many companies require legal paperwork by a law enforcement agency to purchase armor. When purchasing body armor, one should not have a criminal history. That means that it is your responsibility to make sure that you are legally allowed to purchase a bullet proof jacket.
