DALLAS -- Murders are up this year in Dallas, as are robberies, assaults, and burglaries.

A crime report released Friday night by Dallas Police shows violent crime up 30 percent at the start of 2016. Between Jan. 1 and Feb. 29, nearly 1,600 violent crimes were committed, compared to just over 1,200 in the same time frame last year.

Murder is up almost 32 percent to start 2016 and the number of aggravated assaults has risen almost 48 percent. Nonviolent crime is up 5 percent in Dallas.

Under pressure from city leaders to bring the crime rate down, sources say Police Chief David Brown is making radical changes in the department. But officers say the cost is too high for them.

Several officers spoke out to News 8, but asked we conceal their identity for fear of retribution.

"I just don't think the citizens of Dallas know the condition the Dallas Police Department is in."

Multiple sources say Chief Brown is taking officers from all over the department and moving them to special task forces to deal with violent and property crimes.

Hundreds are going to evening and overnight shifts.

"Nobody is happy, and when you have people that are not happy [at] work, we can't provide the citizens the best work that they need."

Officers are in an uproar. They say the moves came abruptly with no warning to them.

"It's effect has really damaged moral. It's damaged our confidence in our command staff and chief. It's damaged how we view our profession."

News 8 spoke with two veteran officers who say they are having trouble dealing with child care issues.

One officer is a single parent with a young son.

"Being a single parent, my child is totally upset and don't know what to do."

Officers say they know they signed up for a difficult job, but many officers have chosen not to promote to higher-ranking jobs with more pay that would require them to work at the will of the chief so they can have a better family life.

"We want to do our jobs we signed up to do -- exactly what we signed up to do -- and we would like to do them, but we want to be respected, as well."

All four major police associations have been meeting about the changes for the last couple of days. The unions are sometimes at odds, but posted a picture of the presidents on Facebook in solidarity.

Officers say there are better ways to deal with the crime rate than turning the department upside down.

"It's obvious they don't care enough about us as people to consider us in their decision. Until we stand up and say 'enough is enough,' nothing will change."

We asked Chief Brown for an interview. He declined and sent us this email:

"We will be formally announcing our response to the 80-percent increase in homicides and 25-percent increase in violent crime this year on Monday."
