A couple of points for you to consider, davep --
1) In THIS case it is unlikely that any of the six cops actually had to put up anything for their bond. Just as bonding companies court favor of the judges with campaign contributions, often they do favors for other folks in making bond (I had a bondsman twice bond ME out of jail at no charge when I had no cash on me to make bond and had to either wait until morning when I could have someone bring cash or wait until a court appearance and an O.R. bond), and in the case of police officers bonding companies will sometimes curry favor with police by either making their bonds without payment (or assurance of payment) or with a heavily compromised charge. And more importantly fellow officers would almost certainly have quickly rallied together to put up property bonds so no one lost anything -- three modest homes would be more than enough to cover a $350K bond, and it would be very surprising if there were not that many officers owning their homes free and clear in Baltimore and eager to help their brother in blue.
2) That is frequently NOT true for schmucks like Freddie Gray who get arrested, often on utterly bullshit charges, such as the bogus "switchblade knife" charge the officers in this case filed against Gray. Those folks, freguently poor and with no one in their family or among their close friends owning real estate or having mush cash themselves, frequently are unable to make even relatively modest bonds of perhaps $5,000, and when they have to await trial in jail, often knowing it will be a year or more before they go to trial on a charge when they might face a maximum of 11 months and 29 days in jail if they were convicted, did not get probation and served every last day in custody (something very unusual, and on misdemenor charges in many jurisdictions those convicted of misdemenors serve no more than 50% of their sentence even if they are a repeat offender), you have tremendous coercive pressure on pervectly innocent defendants to plead guilty at a preliminary hearing or initial appearance or a status conference when he comes to court and learns that if he just pleads guilty right then and there he will be immediately released, though remain on probation. This is the way a great many poor folks in general, and poor, black, inner-city kids in particular, end up with ugly criminal records, often without actually even engaging in the behavior for which they were charged and pled guilty.
My understanding is that in the Freddy Gray case, he had at least 18 arrests between 2007 and 2015 (and since he was only 25, that would have only been his ADULT arrest record, with his record before age 18 likely sealed and unavailable, but also likely to have reflected even more arrests):
March 20, 2015: Possession of a Controlled Dangerous Substance
March 13, 2015: Malicious destruction of property, second-degree assault
January 20, 2015: Fourth-degree burglary, trespassing
January 14, 2015: Possession of a controlled dangerous substance, possession of a controlled dangerous substance with intent to distribute
December 31, 2014: Possession of narcotics with intent to distribute
December 14, 2014: Possession of a controlled dangerous substance
August 31, 2014: Illegal gambling, trespassing
January 25, 2014: Possession of marijuana
September 28, 2013: Distribution of narcotics, unlawful possession of a controlled dangerous substance, second-degree assault, second-degree escape
April 13, 2012: Possession of a controlled dangerous substance with intent to distribute, unlawful possession of a controlled dangerous substance, violation of probation
July 16, 2008: Possession of a controlled dangerous substance, possession with intent to distribute
March 28, 2008: Unlawful possession of a controlled dangerous substance
March 14, 2008: Possession of a controlled dangerous substance with intent to manufacture and distribute
February 11, 2008: Unlawful possession of a controlled dangerous substance, possession of a controlled dangerous substance
August 29, 2007: Possession of a controlled dangerous substance with intent to distribute, violation of probation
August 28, 2007: Possession of marijuana
August 23, 2007: False statement to a peace officer, unlawful possession of a controlled dangerous substance
July 16, 2007: Possession of a controlled dangerous substance with intent to distribute, unlawful possession of a controlled dangerous substance (2 counts)

A) He likely was arrested multiple times on utterly bullshit charges where there was little to no evidence and the prosecution ended up unable to prove its case, the kind of thing which frequently happens when cops make utterly unwarranted arrests;
B) He likely spent a fair amount of unwelcome, and undeserved, time sitting in jail waiting for cases to get before judges who dismissed them after a minimal review of the evidence;
C) He ended up spending a significant sum of money paying bondsmen;
D) It is perfectly reasonable that he would run from police if he saw them, even if he was doing nothing at all wrong at the time.
