Last year, 407 people were charged with assaulting or impeding staff under the Emergency Workers (Scotland) Act.
However, just 296 had charges proceeded with, meaning 27.3 per cent of cases were dropped.
That’s a higher figure than previous years; in 2014/15 around 20 per cent of charges were dismissed before reaching the courtroom.
The statistics were released following a parliamentary question from shadow justice secretary Douglas Ross.
In answering, Lord Advocate James Wolffe QC said some cases may have ultimately been dropped where the mental health of an attacker was an issue.
However, the Scottish Conservatives said the data showed emergency service personnel in the police, ambulance and fire and rescue service needed more protection.
Thousands of paramedics are attacked every year in Scotland, with violence against firefighters and police officers also an ongoing concern.
Some households in Scotland are even blacklisted by the Scottish Ambulance Service, meaning responders can’t enter without a police escort because of previous incidents.
Scottish Conservative shadow justice secretary Douglas Ross said:
“Violence against the men and women of our emergency services in Scotland is an increasing problem, and one the Scottish Government has said it wants to address.
“But these figures show fewer cases are actually making it to court, and those attacked while trying to protect us are being let down.
“And while there will be a reasonable explanation for some of these charges not being pursued, it’s clear someone who attacks a member of the emergency services has more chance of getting away with it than before.
“That will do nothing to deter others who think this sort of despicable behaviour is acceptable.
“Police, fire and ambulance staff do an incredible job in often difficult circumstances, and have to put up with things many of us couldn’t imagine.
“That’s why it’s essential that when they come under attack, our justice system is ready to protect them.”
