Why does the president of the United States have a glass cover when he speaks?

The president of the United States must be protected by bulletproof glass when he speaks, mainly to prevent assassination.

In the United States, when politicians take part in large-scale outdoor activities, they not only travel in bulletproof cars, but also arrange a group of security guards to accompany them. Especially when these characters give speeches on stage, they will be surrounded by a thick layer of bulletproof glass installed in advance.

For example, on July 4 this year, the US Independence Day held a military parade, and Trump gave a speech behind thick bulletproof glass. Although the military parade is considered by the American people to be a waste of money and criticized by the general public, it is a wish of Trump.

As for why such a bulletproof glass shield should be set up, the reason is to protect the president. Because the United States is a special country, their laws allow ordinary people to hold guns. Therefore, among the total population of about 330 million in the United States, the total number of guns has reached 390 million, and one person has one or two guns on average.

Not only American citizens can hold guns, but also those who hold immigrant visas and American green cards can hold guns. This has also led to a large number of people dying in gun cases in the United States, about 30 thousand people every year, and the places where cases are frequent are actually American campuses, which is really scary.

The American people are in danger of being shot, and it is common for the American president to be shot. So far, nine American presidents have been assassinated, five of whom survived and four died.

Because of these terrible assassinations, American presidents also learned the lessons of blood and tears, so for their own safety, they need a lot of bodyguards when they appear in public, and they should also be protected by a thick layer of bulletproof glass when they speak. It's not pretty, but it's necessary.
