THE attempted murder of the former president, Donald Trump has divided the American society in the middle of an election season while many and important questions are raised about the secret services of the country.

The FBI is investigating the incident in which one person was killed and two others were seriously injured.

In the context of investigations and questions that require answers, its director Secret Service has been subpoenaed to testify before a House committee on July 22.

The key questions that need to be answered regarding the security issue are the following:

Why wasn’t the roof where the gunman operated from secured?

It remains unclear how the perpetrator Thomas Matthew Crooks had access to the roof of the building which was about 130 meters away from him Donald Trump .

The roof was designated as a “vulnerable” spot before the incident, according to NBC News, which cited two sources familiar with Secret Service operations.

“Someone should have been on the roof or secured the building so no one could get on the roof,” NBC quoted one of the sources as saying.

In addition to the issue of access, it has been suggested that visibility should be blocked from the point of the roof to where Trump stood.

Were the warnings about the gunman delivered?

An eyewitness told the BBC that he and others had spotted Crooks crawling on the roof with a gun. They notified police, but the suspect continued to attend the scene for several minutes before he began shooting and then being shot himself, he said.

FBI Special Agent Kevin Rojack admitted it was a “surprise” that the gunman was able to open fire.

The county sheriff confirmed that Mr Crooks he was spotted by a local policeman, who failed to stop in time. What remains unclear is whether that information reached the agents guarding Trump.

Officials had already located Crook, according to a senior law enforcement official. As CNN reported, officers thought he was acting suspiciously near the event. This information is disclosed to the Secret Service.

Did the Secret Service rely too much on the local police?

The gunman fired from what was designated a “secondary area” patrolled by local and state officers, not the Secret Service.

A former Secret Service agent said this kind of arrangement only works when there is a clear plan for what to do when a threat is identified.

“When you rely on local authorities, you better plan carefully and tell them what you expect to do in the event of a threat,” Jonathan Vaccru told the Washington Post. The county sheriff admitted there was “a failure” but did not blame any of the parties involved.

Was the event adequately guarded?

The chairman of the House Oversight Committee had said the Secret Service force was “too small,” raising the question of whether local police were sufficiently “trained” to pull off an event like Saturday’s rally.

Jason Chaffetz, who has previously addressed Secret Service failures, told the Washington Post that both Trump and Biden are “high-risk profiles,” but the security presence in Pennsylvania was still insufficient.

The Secret Service denied that a request by the Trump team for its employees had been denied before the meeting.

However, the Washington Post reported that it had seen an exchange of messages in which a former Secret Service officer asked his colleagues how the suspect managed to get so close to Trump, receiving the answer “resources”.

Was Trump removed quickly enough?

Agents who protected Trump weighed in on their reaction, including former agent Robert MacDonald, who said he did a “pretty good job” even though there is no clear “guideline” on what to do in such a situation.

At the same time, the question was raised whether Donald Trump was quickly removed to his vehicle.

Footage of the incident shows them quickly forming a shield around him immediately after the shots were fired, but then appears to stop as Trump asks to collect his shoes. The former president continues to raise his fist to his supporters.

An intelligence veteran told The New York Times that he wouldn’t wait. “If I was there, no. We’re going to leave, and we’re going to leave,” Jeffrey James said. “If it were me, I’d buy him a new pair of shoes.”
