US President Joe Biden unveiled on Wednesday his strategy to reduce gun violence in the country's cities, focused on providing more resources to the police and removing licenses from negligent firearms dealers.

In a speech at the White House and accompanied by Attorney General Merrick Garland, Biden pledged to do more to reduce crime in the country, after homicides rose more than 30 percent last year in major cities, according to studies by the Federal Bureau of Investigation and a national association of policemen.

"Crime historically rises during the summer. And as we emerge from this pandemic with the country opening back up again, the traditional summer spike may even be more pronounced than it usually would be," he warned.

The possible political consequences of this trend are of concern to the White House, which has decided to face the issue head-on – contrary to what other Democratic politicians have traditionally done – and relate it to one of the party's priorities: gun control.

The president said that 5 percent of the country's firearms dealers sold 90 percent of the illegal guns found at crime scenes, and promised "zero tolerance" against those sellers who break the law
