As Gov. Cuomo pushes various criminal-justice reforms, count solidly liberal Albany DA David Soares among the doubters.

Soares, who first won office with help from George Soros and the Working Families Party, sounded the alarm in testimony to the Legislature and remarks at the annual state District Attorneys Association last week.

“Some of these proposals are fraught with problems and could have a negative impact on public safety,” he warned. “We owe it to our residents, businesses and visitors to keep New York one of the safest states in the country, while also balancing the rights of the accused.”

Ending cash bail for most offenses, for example, could mean the end of drug courts, Soares notes: “The way drug courts work right now is that defendants are held on bail and given the option of drug court or jail. If everyone gets presumptive release on drug cases, nobody will go to drug court.”

Ending bail has also had perverse effects in other states. In Maryland, notes the Cato Institute’s Walter Olson, judges responded to limits on cash bail by doubling the number of defendants denied any chance of bail, from 7 percent to 15 percent.

Soares has other worries: Speeding up discovery, for example, may bring more witness intimidation, particularly in gang cases.

His fellow Democrats’ complete control of state government imposes obligations, Soares argues — including “exercising caution.”

At the very least, listen to the experts on your own side.
