There are some really overlook how the security of their bridge set up. Its not bad to have a bridge but projects should always and prioritize security to the highest level.  Cause lying down money on bridges are probably huge and must be protected.  Its sad that $1.4b falls on the hand of exploiters alone.  I wonder if the suspects are the same on all those incident.  If yes,  then he must be really an asshole for taking up people's money just like that.
