The attackers usually call the emergency services and fool the dispatcher into sending personnel, and thus the attacker manages to take advantage of the response protocol of the emergency service and attack their victims.
The swatting act is highly dangerous because in such situations the law enforcement personnel assigned to respond to the fake emergency are trained to use lethal force. This could cause innocent people to suffer injuries or even become a reason for their death.
Many cases occurred when attackers called law enforcement and hoaxed them into responding to a fake emergency situation and causing injury to people and death.
This technique could also be used in a situation where the attacker makes a bogus report of an emergency situation perceived by law enforcement agencies as highly severe and they have to send a lot of staff to deal with the situation.
This will cause most of the response personnel to be engaged in this situation, and the attacker could take advantage of this and perform some other illegal and dangerous activities elsewhere knowing that the response personnel are engaged elsewhere and that it would give the attacker more time to do their evil deeds. This shows that swatting can also lead to other dangerous activities happening elsewhere.
By law, in many countries, making bogus reports to emergency services is a criminal offense. This is because it costs government money and resources to send emergency personnel to handle serious emergency situations. In some countries, the swatters have to pay the full cost of the emergency response that can be up to $10,000.
An example of a swatting attack is the one that happened in the U.S. when a man reported a fake hostage situation occurring at an address he believed to be a guy with whom the man was playing a computer game and with whom he had got into an argument. He just called the police, gave them a random address, and created a fake situation that triggered the police response.
They thought the man had killed his own father after the police arrived at the address and took other family members hostage. The man came out of the house knowing nothing about what had happened, and after he came out, he dropped his hands unexpectedly and was shot by the police.
This is how dangerous swatting is and should never be practiced by anyone as it can endanger the lives of other people. People should also be aware of this dangerous swatting process so that if they see some law enforcement or other emergency services outside, they can act accordingly and communicate their message correctly to the response teams so that they can understand whether a person is innocent or not.
