The USA TODAY/AP/Northeastern University mass killings database has tracked a dozen mass killings in 2021 that have left 68 people dead and 15 people injured. Three of those events happened in just one week.

Co-led by David Lazer, a political scientist at Northeastern University in Boston, Massachusetts, researchers have been conducting surveys of as many as 25,000 people per month, across all 50 US states, as well as collecting information on Twitter use by nearly 1.6 million people.

“The problem with that model is that an actual risky situation, where an officer might actually be injured, represents 1 to 2 percent of the interactions an officer is ever going to have to do,” said Jack McDevitt, a professor of criminology and criminal justice at Northeastern University.

Some epidemiologists are arguing the government should have been better prepared from the beginning to respond to hot spots with vaccines to slow the spread of more transmissible variants. “We should have held a tranche of vaccines in reserve for surging to variants,” said Samuel Scarpino, an epidemiologist at Northeastern University.

“It takes away any ambiguity about whether individuals should be vaccinated,” said Kenneth Henderson, the chancellor of Northeastern University in Boston. “It also provides a level of confidence for the entire community that we are taking all appropriate measures.”
