A protest action by Trump supporters in Washington turned into a storming of the Capitol on Wednesday evening.

The perpetrators broke through various police barricades and occupied wings of the building.

In the United States, the first question marks are raised about the - relatively very low - police deployment.

In particular, a comparison is drawn between the events of Wednesday and the Black Lives Matter protests of last year, in which the heavily armed riot police were often present in large numbers and also intervened sharply while there was less reason to do so.

The police, the Pentagon, and the Capitol refuse to answer questions from

.

The force to secure the building normally includes about 2,000 officers and was last expanded after the terrorist attacks on September 11, 2001, the paper writes.

Sources tell American media that local authorities, headed by Mayor Muriel Bowser, were simply not prepared for a protest with such an impact.

Previously, similar protests were taken into account as in November, when small far-right and left-wing groups clashed, according to

The Wall Street Journal

.

That is why initially 'only' 350 members of the National Guard were put on alert, while Mayor Bowser was forced to deploy the entire regiment later in the evening.

Nearby states sent their reservists, while FBI agents and the US Secret Service were also called in.

'Capitol police are inexperienced, no storming taken into account'

They had to rescue the now-encircled Capitol police.

Agents hid in halls with Congressmen and aimed their weapons at perpetrators of violence trying to enter.

In conversation with the newspaper, a retired FBI director states that the force is too inexperienced, because such incidents almost never occur.

"It wasn't until Trump supporters entered the Capitol that reality seemed to get through."

Police chief Robert Contee said in the night from Wednesday to Thursday that at least fourteen officers had been injured.

One of them is in a very critical condition, because he has moved into the crowd and has been attacked.

Bowser argues that the explosion of violence is the result of President Donald Trump's "provocative words".

This statement was echoed by Trump's successor Joe Biden.

“The words of a president mean a lot, no matter how good or bad that president is. They can inspire residents or prompt them to take action,” said the president elect.

Prior to the storm, Trump addressed another crowd.

"We are going to walk up to Congress and encourage our senators. We will never give up," Trump said.

That slogan was later left by his supporters on a paper in the office of Nancy Pelosi, the Democratic Speaker of the US House of Representatives.

Members of the US Congress promise to investigate police deployment

Some members of the US Congress have already been very critical of Wednesday's police deployment.

Democrat Zoe Lofgren says the storm has revealed "serious security problems".

She promises an independent investigation into the police deployment.

Party rival Val Demings, a former police chief, believes that it has been "painfully" demonstrated that "security services are not prepared for major incidents".

The corps was understaffed and there was no clear plan, Demings believes.

Democrat Tim Ryan already wants to go a step further.

"Obviously after this shame some people will lose their jobs."
