Officer Sean Gannon is being buried this morning down on the Cape, and people are asking, how was this dirtball Thomas Latanowich still on the street with 125 strikes at the age of 29?The answer is, welcome to Massachusetts.Officer Gannon was murdered in cold blood last Thursday. Less than 24 hours later, in a bitter irony, a moment of silence was observed at the State House Friday afternoon, just before Gov. Charlie “Tall Deval” Baker signed into law a “sweeping” — read, terrible — reform of the criminal-justice laws in Massachusetts.
